Arimaa is an abstract strategy game for 2 players, similar to the likes of chess and Go. The game is played on an 8x8 grid with 4 trap tiles. Each player has 16 pieces of varying strengths. In order from strongest to weakest – one elephant, one camel, two horses, two dogs, two cats, and eight rabbits. The goal of the game is to be the first player to move a rabbit to the opposing side. Alternatively, a player can win by removing all opposing rabbits from the game or immobilizing them from doing any legal moves.
Pro Fluid gameplay
The 4 moves per turn gives Arimaa's tree of possible moves a very high branching factor. (It was invented for AI programmers as a game more difficult to program for than chess, but easier than Go). You can't think several turns ahead like chess (the space of possibilities is too big), instead you have to think in terms of distances and capabilities, giving Arimaa a very fluid feel.
Pro Easy to learn
Arimaa is a game suitable for both young and old, it was made to be intuitively simple but with a lot of depth. Even the setup follows this premise - you set up the figures in two rows like in chess, but you can place them in any way you like.
The rules are simple – in your turn you have four actions. You can either move a figure four times, move four figures one time, or do any combination in between. All figures can move forwards, backwards, and sideways apart from rabbits who can’t go backwards.
You can use two actions on a stronger piece to push or pull your opponents’ weaker figures. These stronger figures also “freeze” adjacent weaker pieces, preventing them from moving unless there’s a friendly piece next to them. If a figure happens to walk into one of the four trap squares or get pushed/pulled into one without a friendly piece next to it, then it is removed from the game. The first player to get a rabbit to reach the opposing side wins. The game can also be won by removing or immobilizing all your opponent’s rabbits.
Pro Active online community
The official site of Arimaa is quite lively and features reviews, downloads, the latest news, an active public forum, and much more. There’s even an online gameroom, so you can play Arimaa against computers or other people in either turn-based or real-time games. There are many people online, so it shouldn’t be a problem to find a game.
Con Requires constant engagement
Arimaa can get out of hand quickly because there’s pretty much no way of predicting how future turns will play out. This is because it’s significantly harder to pinpoint four actions that your opponent might do as opposed to one action in similar games to Arimaa. Due to this the game requires the players to continually pay close attention to what they’re doing, which isn’t inherently bad, but can be a bit problematic for people with shorter attention spans or for people who don't want to take the game too seriously and just play it for fun and socialize meanwhile.
