Hex Stack

Drop coloured tile stacks onto a hex board. Matching tops merge, and six in a row clear. Keep space free and chase a high score.

How to play

Each turn you have three pieces, each a small stack of two or three coloured tiles. Pick one and tap an empty hex to place it.
When touching hexes show the same colour on top, their matching top tiles merge onto the larger run. Merges can chain into further merges.
Any run of six or more tiles of one colour clears from the board and adds to your score.
When all three pieces are placed you get three new ones. The game ends when every hex is occupied.

Place pieces beside a matching colour so they merge straight away and free the hex you used.
Keep one or two hexes empty as a buffer. A full board ends the game.
Build one tall stack of a single colour, then top it up to reach six.
Mixed pieces let you set up two merges at once. Look at where the top colour will end up.

Which run moves when two stacks merge?: The smaller matching top run moves onto the larger one. On a tie, the neighbouring run moves onto the piece you just placed.
How is the score counted?: Your score is the number of tiles cleared. Your best score is saved on this device.
Is there a daily puzzle?: No. Hex Stack is an endless score game with random pieces.
