Dominoes, the way it is played at the table.
Block and Draw, against an opponent that actually thinks about which end it is leaving open. When you are stuck, the coach will tell you what it would play and why, in plain English.
Two games, not one
Block is the pure version: seven tiles each, no draw pile, and if you cannot play you pass. Every tile you hold is information someone can read off you. Draw adds the boneyard, which softens the bad hands and lengthens the game.
A coach that shows its work
Tap Analyse board and the game names the move it would make, ranks the reasons behind it, and tells you the trade-off you are accepting. It is the same evaluation the Sharp opponent uses, so the advice and the opponent can never disagree.
No language model, no network call. The explanation is generated from the numbers the engine actually computed, which is why it works with your connection off and why it cannot invent a reason for a move it did not pick.
Your games stay yours
