As someone afflicted by an intellectual short coming called Dyscalculia (the number/math equivalent of dyslexia) I’m extremely restricted when it comes to games using numbers or requiring a mind capable of more than simple math so games like this require the manipulation of symbols or images are ideally suited to someone like me. As if to compensate for me having dyscalculia I learned to read at a very young age - I began school at 5 already well advanced in my ability to read compared to other children also starting school. This neat little game could have been invented with folks like myself in mind. ### 3/5 — Tic Tac so so *2023-02-11* Briefly interesting twist on classic Tic Tac Toe. Begs for ability to play with another human. Still, little opportunity for new strategy. Move first, easily win. ### 1/5 — Waste *2022-08-12* Beat game in five minutes. No option for two players. Garbage. ### 5/5 — Not bad *2022-02-09* Ok ok ok ### 2/5 — Simple minds *2021-07-13, version 1.9* Very simple basic game . Good for 6 year old. ### 2/5 — Deleted after 10 minutes *2021-07-10, version 1.9* Its a good variation on noughts and crosses, well put together but its basically still noughts and crosses. Play it for 10 minutes then You find every level is exactly the same so you delete it. ### 5/5 — Beautiful and simple *2021-07-09, version 1.9* A pleasant surprise ! Beautifully minimalistic design and stress free gameplay. Well done Developer! ### 5/5 — Fantastic extension to the classic game! *2021-06-20* Now why didn’t I think of this! Lovely way to avoid the many draws that the classic Tic Tac Toe game causes - when it is impossible for either side to move, and hence a draw. Just when and where the classic game results in a draw, this version lets the game continue to more logical end where the goal then becomes to EITHER get the classic three in a line, or gain a win by forcing the other player into a situation where neither can they place a piece down nor move an already placed piece to an empty space where it is legal to do so resulting in a win for the other player. It is still possible for a draw to occur I think when neither side can move or place a pice down but I think this kind of draw - unlike the classic game - is much less likely to occur and wins are more likely. It is straightforward in the classic game to result in a draw after a draw but with this extension the result will be more outright wins and far less draws! ### 1/5 — First Player Always Wins *2020-06-24* I’m on level 9 and the AI always losses if I go first. Similarly, I lose if the AI goes first. Not that interesting, frankly. ## Frequently asked questions about Achi ### What is Achi?
