Full Report for Boop. by Scott Brady

Full Report for Boop. by Scott Brady

A deceptively cute, deceivingly challenging abstract strategy game for two players.

Generated at 6/14/23, 4:27 PM from 1000 logged games.

Rules

Representative game (in the sense of being of mean length). Wherever you see the 'representative game' referred to in later sections, this is it!

These are abbreviated rules. the full rules are available to download on BGG.

Goal

Make a line of three Cats to win.

Play

Each player starts the game with 8 Kittens in their pool.

Each turn, a player adds a piece to the board from their pool, then boops (pushes one space) any adjacent pieces.

Booping

Promotion

When a player makes a line of three or more, they choose one such line and remove those Kittens from the game. They add a corresponding number of Cats to their pool instead.

If all 8 pieces belonging to a player are on the board, they may remove and promote a single piece.

HistorianTeacher8A nice little two-player abstract game whose visual simplicity masks some really great strategic gameplay. The artwork is endearing, and the game teaches quickly. A definite recommendation for fans of abstracts.

bunoc7Core abstract game. If you match your piece together, they will "boop." away. So the way to get them close is place them apart and boop. them together later. Can be play with any pieces/cube on a 6x6 grid

dcoffer3The concept is cute but the theme of cats is all that's going well for this game. A price of anything over $20 is crazy for a game played on a 6x6 grid with a few cat meeples thrown in. I can't wrap my mind around anyone paying $40 for boop. The movement is basic as you try to boop your opponents kittens off the bed while aligning your own to transform them to cats. I'd much rather play Onitama or even Chess before boop. My fuzzy friend and I are just going to have to pass.

HollaMonkey6Game was interesting like an advanced version of tic tac toe, would have rated it higher except the components are annoying. The cats would constantly fall down and then if accidentally bumped the quilt it knocked everything over and off. Maybe bigger cats or less quilt.

adesireg7Kids Overpriced. It should be a $15-$20 game max. Game is ok.
stuffbybez9.1Very much enjoying. + simple, intuitive + 'easy mode' is still a worthwhile game + with the advancing it starts become more strategic (not just tactical) + cute - is there a hypothetical stalemate? Will be curious to know how it feels after 100 games. The heart of a brilliant 2p abstract, with a veneer of cute.
NicoleBrady10There's a lot more strategy to boop. than the cute little cat and kitten meeples would lend you to believe. The more you play, the more you'll see the depth required to win against more strategic players. Of course, part of the charm of this game is the feel you get from playing it in person. If you've only had a chance to play digital versions then you're really missing out. Check with your local game store to see if they have it in stock or will be restocking soon.

DYE_LON10Delightful, cute, and fun. Definitely solid excitement for all ages; highly recommend making cat noises during gameplay! Hilarious! Easy to teach, addicting to replay. Great short games! If you keep hitting an impasse, you're probably not implementing much strategy.

dearphilly7Super cute game! But won't buy personally as I don't get many 2 player opportunities and box is quite bulky. Nice wooden components reflected in price. Takes a while to improve so need to play someone of the same level as you. Cats love boxes IYKYK ;)

pbjblitzkrieg9Brilliant game all around. Love the nuances of having a kitten vs cat. Also love the multiple winning conditions. I really wished there were cards or something to “Jazz” up the gameplay more but this game is VERY easy to learn.
brothervm7Couple of games and it's fun and bouncy and whimsical. I'm sure there's some strategy here, but also seems there is a good chance at reaching an impasse as our cats danced around each other for 60+ turns until someone made a mistake.
HercMec10
grasa_total5I've struggled a little with other "play a piece, it moves other pieces" abstracts because so often it feels like you have to do everything the hard way. You can't just put a piece where you want, it'll move the piece you wanted it to be next to! [i]boop.[/i] has the same element at first, but then takes it away. And it turns out I miss it! Once you have two kittens in a row, you can just drop a third kitten to make the row of three, since with another cat in the way, there's no booping. So [i]boop.[/i] seesaws between making your life too hard and making it too easy. It also moves from too crowded to too empty a little fast, as making any row of three leaves your position suddenly much less interesting by removing all three pieces! The sparring for position is still interesting; at a first approximation, the opponent can easily and severely interfere with anything you want to do, so the question is how valuable you can make the ruined scraps of your previous plan. That's a gametype I like. But at very few moments was this in the sweet spot for implementations of that type. Update: The designer wrote, in a BGG design diary, that originally the game only had one type of piece, and ended with a line of three. I think that version would be better; the mid-game reset as players get cats really doesn't do much for me. Either way, I like Phil Leduc's [i]Momentum[/i] more than this.

hyggeministeren2Poorly designed, boring and repetitive. But at least we got some cute cats to look at eh. Next time the designer should focus on gameplay first and aesthetics second.

Edysseus Games8étonnamment excellent petit jeu abstrait
jessea38The game is totally abstract and could, in fact, be played with pennies, dimes and lines in the dirt, but it is rare and refreshing to find a game where such attention has been paid to the details, ensuring that the backstory matches the abstract mechanic. While it could be played without the cats, somehow I don't think it would be nearly as much fun.....

biggoatgruff10Too cool for school. Tic tac toe on steroids. I played with another old foggy on Christmas eve and the kids never got a chance because we just kept at it for hours. Finally the fire went out and we went to bed. I dreamt of kittens!

GrapeGrrl8The cats are adorable. The game premise is adorable. It seems like it should be pretty straightforward play to win. But this game is deceptively hard, and you really need to play a few times before you start to get the hang of how to win. But I'm getting there, and in the meantime I'm having a lot of fun. PS I love saying 'boop' whenever I place one of my kittens on the board.

tabletopsubmarine10Such a wonderful abstract! Good in person and on the table. Rewards multiple plays and is welcoming to all gamers!
Bloocoast5Fun twist on checkers but games can get exhausting and long.
ciggie4A thinky abstract of playing a piece and it moves the other adjacent pieces. It's a very cute theme, but I felt like I was always playing defensive against my opponent and I could never get 3 kittens in a row to upgrade it to a cat so I never had a chance to win. I imagine if you like chess or similar games you'd like this, but for me it's a hard pass.

charleaux5Very cute theme but the game is just too abstract for my taste as I'm terrible at trying to plan a few moves ahead. The fact that your opponent is constantly moving your pieces definitely doesn't help. While it's not my cup of teas, fans of spatial abstract games would probbaly dig this one a lot.
HezzaN/AA game with kitties called Boop?! I've done zero research, but don't feel any is needed. Take my money! How do I get a Boop pin?! *Update. Played twice, lost twice. Fun game though!
evanvariano7You "own" this if you have a checkerboard. Though I like cute cats and the word boop, I wish a different theme were on this game. Great to see an abstract perform so well in the marketplace, though! The early game feels like "trying to nail jello to a wall" which is not my favorite type of play, but when a good move comes together, it's quite satisfying. The shockwave mechanic feels like hitting, which I think is why the first step in the ladder of strategy is so accessible. The designer noted that people don't report feeling "too dumb for the game." This is really really important for getting new players to engage in a 2p abstract. I think the reason why people are pleased to engage is because there is usually an option to move stuff around forcefully, which gives a feeling of agency. "I can't think good but I can hit hard."
janglemangle4playing boop has one problem: i need someone who likes thinky abstracts but also likes saying boop and playing with cute cat components! it's either dead silent thinky, or cute booping no thinky!! and after, "that was cute, onto the next game." there is untapped potential here for an abstract i enjoy rather than a one-and-done experience

CDRodeffer5I want to like it, because I generally do like abstract strategy games, and this type of forward thinking game is the sort I generally play well. But I wonder if I'm missing something. Even so, it should make for a good game to include in my annual tournament of abstracts, and it might become a prize there.
Carnage9946A cute little 2 player abstract game that feels quite random at first, but the strategy starts to emerge with multiple plays. It feels a bit repetitive at some points, as each player successively bumps the other player over multiple turns. It isn’t great but it isn’t terrible either.
ericbinnyc6.5A clever, if a bit unintuitive at first glance, abstract strategy game for two players. Not for cat lovers that don't also love brain-burning puzzles.
vkshravi8810
Kiwimaru10Pros: Depth of strategies born out of simple rules Medium Duration of Gameplay: Not too short. Not too long. Unique Mechanic: The Booping Mechanic is new to me. Theme: Cuteness and Adorableness. Cons: Too costly - The cost likely comes from the quilt. But the game concept is so simple that I feel like it should be cheaper.
behr774.5Cute abstract that I wouldn't have played if not for the very cute theme. Very similar to chess/checkers/go in some ways which just isn't my type of game. Likely has more depth if you continued to play it many times, but that's not something I will end up doing. Not for me.
Demiss6.9Not my cup of tea, too streamlined perhaps ? (but that's also a quality obviously)
Silver Fang9
AmassGames5Oof, certainly a longer combinational abstract strategy game. A winning n-in-a-row game takes a long chain of combo moves. Fairly infuriating and longer than I feel it needs to be BGA www.youtube.com/amassgames for abstract strategy (and seperately) two player playlists
BlueWaters9
heathbarATL7(BGA) Cute and thinky abstract.
drkenfp10Brilliant, elegant, and adorable.
DaLeach10Amazing game.
Born-of-Ashes8Such a cute theme! And it has super simple rules which lead to incredible depth. Even though it is a familiar three-in-a-row game, you’ll have to relearn all the tactics since threats are so easy to neutralize and in order to group your own pieces you need to come at them in a roundabout way. There is a rare chance for an endless loop, but when that novelty wears off you just break the cycle. I do feel like it can have a bit of a runaway leader if someone goes longer than 3 turns having cats while the other player doesn’t, but the learning curve is one game, so that is unlikely to be a factor after your first game.

drewtimmer2This is the most aggravating game. It's all just obnoxious "gotchas" and "take thats."
holf8三秒學會規則,過程卻很激烈的對弈遊戲!玩家一開始只有小貓棋子,當棋盤上三隻小貓連成直線可以變成大貓,遊戲目的是將三隻大貓連成直線,或是將所有的大貓放到棋盤上,而這遊戲的名稱來自於當你將棋子放到空位時,會將旁邊的所有棋子向外推一格;小貓只推得動小貓,大貓兩種都推得動。規則簡單,美術又萌,遊戲內容也是不簡單,除了一開始可能會因為想生出大貓造成一點僵局,也考驗了玩家間的實力拉鋸─不過一但眼殘也是會一敗塗地的!

bluesol8Wonderful abstract game that has layers of strategy that are not obvious, partially due to the cuteness of the theme.
hiimjosh6One of the best light n-in-a-row games. You are trying to get 3-in-a-row with level 1 pieces which gives you level 2 pieces. The goal of the game is to get 3-in-a-row with level 2 pieces. When you place a level 1, it bumps all level 1 pieces in all 8 directions one space further. A level 2 bumps level 1's and 2's. It's a well-done game. I would happily play it any time and may even choose to come back to it every now and then. Worth checking out especially if you play with family. Label: Good But Not Great

pdowen39Deceptively cute abstract. I got talked into picking this up at Euroquest 2022 (Annapolis), and I am not disappointed. My wife seems to like it (even though she doesn't generally go for open-information zero-luck abstracts), and it's really clever. Hope we get to play more.
brutusbear8Cute Abstract game. Lots of strategy here. Bit tic tac toey. othello, reminds me of dragon face another good abstract cute theme keeper. $35 retail msrp seems high for what you get.

CHRISDH7This is a cute introduction to abstract games. Turns are quick and simple but still allow for a good amount of strategy. I can see playing this with family but it's too light for gamers.

Kolomogorov Complexity Analysis

Size (bytes)29971
Reference Size10673
Ratio2.81

Ai Ai calculates the size of the implementation, and compares it to the Ai Ai implementation of the simplest possible game (which just fills the board). Note that this estimate may include some graphics and heuristics code as well as the game logic. See the wikipedia entry for more details.

Playout Complexity Estimate

Playouts per second46805.96 (21.36µs/playout)
Reference Size2745744.10 (0.36µs/playout)
Ratio (low is good)58.66

Tavener complexity: the heat generated by playing every possible instance of a game with a perfectly efficient programme. Since this is not possible to calculate, Ai Ai calculates the number of random playouts per second and compares it to the fastest non-trivial Ai Ai game (Connect 4). This ratio gives a practical indication of how complex the game is. Combine this with the computational state space, and you can get an idea of how strong the default (MCTS-based) AI will be.

State Space Complexity

Not enough data for an accurate prediction, or game does not support hashing

State space complexity (where present) is an estimate of the number of distinct game tree reachable through actual play. Over a series of random games, Ai Ai checks each position to see if it is new, or a repeat of a previous position and keeps a total for each game. As the number of games increase, the quantity of new positions seen per game decreases. These games are then partitioned into a number of buckets, and if certain conditions are met, Ai Ai treats the number in each bucket as the start of a strictly decreasing geometric sequence and sums it to estimate the total state space. The accuracy is calculated as 1-[end bucket count]/[starting bucklet count]

Playout/Search Speed

LabelIts/sSDNodes/sSDGame lengthSD
Random playout46,534993,654,6997,0497919
search.UCT46,5451,0564210

Random: 10 second warmup for the hotspot compiler. 100 trials of 1000ms each.

Other: 100 playouts, means calculated over the first 5 moves only to avoid distortion due to speedup at end of game.

Mirroring Strategies

Rotation (Half turn) lost each game as expected.
Reflection (X axis) lost each game as expected.
Reflection (Y axis) lost each game as expected.
Copy last move lost each game as expected.

Mirroring strategies attempt to copy the previous move. On first move, they will attempt to play in the centre. If neither of these are possible, they will pick a random move. Each entry represents a different form of copying; direct copy, reflection in either the X or Y axis, half-turn rotation.

Win % By Player (Bias)

1: Ginger win %58.20±3.08Includes draws = 50%
2: Black win %41.80±3.02Includes draws = 50%
Draw %0.00Percentage of games where all players draw.
Decisive %100.00Percentage of games with a single winner.
Samples1000Quantity of logged games played

Note: that win/loss statistics may vary depending on thinking time (horizon effect, etc.), bad heuristics, bugs, and other factors, so should be taken with a pinch of salt. (Given perfect play, any game of pure skill will always end in the same result.)

Note: Ai Ai differentiates between states where all players draw or win or lose; this is mostly to support cooperative games.

Level of Play: Strong beats Weak 60% of the time (lower bound with 95% confidence).

Draw%, p1 win% and game length may give some indication of trends as AI strength increases.

1st Player Win Ratios by Playing Strength

This chart shows the win(green)/draw(black)/loss(red) percentages, as UCT play strength increases. Note that for most games, the top playing strength show here will be distinctly below human standard.

Complexity

Complexity10^69.21Based on game length and branching factor
Samples1000Quantity of logged games played

Computational complexity (where present) is an estimate of the game tree reachable through actual play. For each game in turn, Ai Ai marks the positions reached in a hashtable, then counts the number of new moves added to the table. Once all moves are applied, it treats this sequence as a geometric progression and calculates the sum as n-> infinity.

Note: most games do not take board rotation and reflection into consideration.
Multi-part turns could be treated as the same or different depth depending on the implementation.
Counts to depth N include all moves reachable at lower depths.
Inaccuracies may also exist due to hash collisions, but Ai Ai uses 64-bit hashes so these will be a very small fraction of a percentage point.
