Full Report for Adaptoid by Néstor Romeral Andrés

Capture 5 enemy pieces to win

Rules

Each turn, perform the following actions in order:

  1. Move (optional): move a piece up to as many spaces as it has legs; a piece may capture by replacement if it has more pincers than the opposing piece; if both pieces have the same number of pincers, they are both captured.
  2. Grow (required): add a leg or pincer to an existing piece, or add a new piece adjacent to an existing one
  3. Starvation: enemy pieces with fewer adjacent empty spaces than the number of limbs they have are captured

The first player to capture five enemy pieces wins; if both players reach this goal simultaneously, the active player wins.

mrraow8There is a wonderful balance here between the power of the pieces and their vulnerability. Thematically, it works very well also. Rating may go up with further play. My one reservation at present is whether the first player has a significant tempo advantage.
bravucon6Not bad at all, but Adaptoid is a very hard game to play from time to time. I prefer more forgiving and less tight abstract games.
Hollyhock7The deluxe edition is expensive, but it is worth it! Adaptoid is a very nice and refreshing abstract. Each turn, your game pieces may grow in strength or speed, but at the same time they become more vulnerable to death by starvation. Strong pieces are most powerful when the board is empty, but as soon as new pieces spawn or the battle reaches a table border, strong pieces become suddenly weak, as smaller and faster adaptoids are able to kill them by surrounding and starving them. So while you combat, you have to balance properly the evolution of your pieces and avoid stacking all evolutions on the same dude.
thepackrat7A good game, players seek to move and grow their adaptoids around the board to capture the opposing side, of course, you capture through starvation as well so the more powerful the creature, the more easily it starves to death. A little too paralysed by thinky moves, but still an interesting different little abstract that goes strongly against intuition of what you should do. Probably area control under the hood. With a few more plays, there are multiple different strategies and ways of playing simply to react to the other player. Suddenly the 'obvious' bad moves can be useful after all.

dolzandavid7A brilliant abstract that actually makes a perfect sense thematically. Simple rules, engaging games, coupled with an ingenious rule to make the strongest pieces the most vulnerable. I am enjoying this game immensely.

ellyssian8Played this when I first got it, and didn't comment until years later... It's a good lightly themed abstract.
Andy Parsons7An abstract with a well integrated theme, if such a thing is possible. Building up a critter so that it can move faster and/or fight better also makes it more vulnerable as it needs to be surrounded by more empty spaces. That's the very clever core of this game. Strategic options seem abundant. My one concern is that the first player advantage is quite strong. Can't say I'm a fan of the mouse mat board, though the adaptoids themselves are nicely done. It was much too tight a fit squeezing everything into the pencil case the game came in, so that has been dispensed with.
krainerN/Awant super adaptoid most of all
out4blood6I like this game. It has some neat mechanics that fit in directly to the theme - as if an abstract can have a theme! - that also creates some interesting decisions.

brandoncorgi10One of the most interesting and original game designs that I have ever had the pleasure of playing. Masterpiece! Now if I can only master the strategy! Please note that my comments are for the "Super Adaptoid" edition which is beautiful and very functional. The high cost is justified.
Wentu6.7Original mechanics, quite interesting indeed. Fantastic material gives you the feeling of something moving and pinching. Unfortunately , it seemd to me quite a brain-burner in the negative aspect of the word. It seems, from a 2 plays experience, that after you win the first "skirmish", it's much much easier to win the entire game. it seems rather difficult to catch up .... i'll play it again for sure

barnyams368Really good abstract with theme. Your bugs may move, attack or develop themselves in order to kill a certain number of the other side. But the stronger you are, the more freedom you need... Really clever game, to play slowly, with a nice presentation.

MikeBwithoutadot7.5Bought at Essen '09. Good looking 2-player abstract, comes with a foldable and washable board. Easy to take along. Very nifty mechanism: the "better" your pieces get, the easier they are too kill. Very thematic game for an abstract by the way. NL: 2 persoonsspel waarbij je elkaars "adaptoids" (een soort aanpasbare microbes) probeert op te vreten.
patchwerqN/AAwesome! A really cool 2-player abstract strategy game! Yet again, a great Nestor game with super components and storage! This game is like no other, it's tricky and fun creating little clever Adaptoid creatures that move and attack! Having to feed the little guys is the tricky part! You might create a wonderful little Adaptoid or more, but if you don't leave enough surrounding spaces free...the poor thing will starve...making your opponent gain points! While my wife is not fond of abstract strategy, she enjoys this game quite a bit!

Furan4Interesting design, although it lacks something.
HeyswyndonN/AImplement with IceHouse: Rules card needed, Each player: 2 stashes (Lights & darks) etc. 1: Raygun (for capture) 2: Base 3: Boosters (for movement) Mining: must have space to mine (eat) Upgrade (or your oppentn getws piece) 2x can trade one of your pieces for your base captured by opponent. (Gives effective 12 bases) Use hex on Martian Chess back, or Poker Chips for bd.
franchi8.5Reminds me of Dvonn or Tzaar (games I like), in how 'strong' pieces become fragile, but here there is a theme too.

russ6I wanted to like it more than I did: the physical implementation is too cumbersome (trying to add new legs and claws to an adaptoid; trying to move an adaptoid without its legs or claws falling out). This distracted us from the gameplay itself.

D Beau6.5Relatively low rating is after one slightly unsatisfactory play, but I expect it to raise with more. The rules seem (and are) quite simple and elegant, yet we had some confusion regarding a few of the details (which were only clarified afterward, by checking threads here). The pieces are on the small side, yet an adaptoid with appendages is too large to be contained by the circular spaces. Add to this the necessity (since they're fragile little things) of sliding your pieces around, rather than picking them up, and the game becomes somewhat fussy, with pieces being pushed around, errant appendages falling, and needless repositioning. With all due respect to Nestorgames, this game really should have chunkier pieces (which [i]are[/i] available, but for an exceptionally high price). Still, it's an interesting game, and shows signs of greatness, so it's worth putting up with a bit of bother. Charity; St Gall's 2019
drbobjack7Adaptoid is a nice little movement game that has more subtleties than it seems. The core of the game is a set of pieces with ever-growing powers that feature chesslike capture, but as pieces grow stronger they require more area. This leads to stronger pieces moving through space, trying to capture loose pieces while keeping enough territory to feed and produce more pieces also vulnerable to capture. The scoring system (first to capture 5 pieces) is perfect for what the game is, forcing weak pieces to be carefully husbanded by stronger ones. It's a cool dynamic, if more limited than the best abstract games. And the nestorgames production is both lovely and perfect for the game.

Ottia9Quick, addictive and just as compact as anything on the GIPF series, Adaptoid has two players putting their own pieces onto the board and then developing them in order to eliminate rival pieces either taking them or occupying a certain quantity of spaces around them. Players must "grow" or develop pieces in every turn and the more powerful pieces are, the easier they can be attacked, so that the first movements in a game (especially by the first player) can lead it to very different routes: one powerful piece sweeping the board, many slow pieces building and/or eroding barriers, suicide attacks... The whole catalogue of Nestorgames is full of refreshing, portable ideas making any fan of abstract games dribble in anticipation; Adaptoid might be its very highlight.
Kaffedrake4In theory there's a lot of ways to equip and position your pieces, but in practice your moves are mostly constrained by your opponent's - and in particular the second player is responding to the moves of the first, as there seems to be a significant first-player advantage. It also seems the game would often be settled after the first mistake, since a player who is ahead can just go for exchanges.
Nalex2228I'm not usually a fan of abstract games but this is the exception. A brilliant little abstract with theme! Plays quick so multiple plays in one sitting is possible, allowing you to try out multiple strategies. One of the many gems in the often overlooked nestorgames range.
anibalCartago7
KrisVerbeeck7Well I respect Nestor as a publisher making lots of abstracts available through his company. This was a really tough evolution game where it easy to make a mistake. As a design it really works. Pretty good
ericbjohnsonN/AGaming:
s3rvantN/APlayed a few times, didn't care for it.
dbucak9A cool abstract with, paradoxically, a well fitting theme. There are many trade-offs to balance, do I go with fighting power or mobility, a few strong units or many weaker ones. Adaptoids with more legs and pincers can move further and fight better, but are more vulnerable to starvation. There are two ways of capturing, a chess-like move-on-top-of capture and a go-like take-away-liberties capture (eat vs. starve in terms of the theme.) This makes for some interesting tactical possibilities. So far I'm enjoying it very much.
voynitsky3I had to point on a doll to show where the game made me hurt.

Level of Play: Strong beats Weak 60% of the time (lower bound with 90% confidence).

Draw%, p1 win% and game length may give some indication of trends as AI strength increases; but be aware that the AI can introduce bias due to horizon effects, poor heuristics, etc.

Kolomogorov Complexity Estimate

Size (bytes)33480
Reference Size10293
Ratio3.25

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 second21061.23 (47.48µs/playout)
Reference Size372093.02 (2.69µs/playout)
Ratio (low is good)17.67

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.

Win % By Player (Bias)

1: White win %61.70±3.05Includes draws = 50%
2: Black win %38.30±2.96Includes 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.

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.

Computational Complexity10^5.51Sample quality (100 best): 80.16
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.
