I always play the 3-tile "strategic variant". But I can't seem to see how many tiles the other person has at the end of the game. How can I work out if they have 2 turns left, or 1, or 0...?
The game tells you at the top right (by your name marker) how many tiles are left to be played. With some quick maths, you can work out roughly how many tiles each player has left.
To the best of my knowledge, there is no on-site way of seeing this exact stat, since the game isn't open-hand.
