HexaStone is a simple game. Swipe left or right to rotate the board and let gravity (or yourself) combine the hexagons with the same number. Reach the highest number before the board fills up.
Options include different sized boards, boards with or without a central obstruction and manual gravity.
Modelled on the primary mirrors of segmented mirror telescopes but unlike them the smaller the board the harder the game.
