Block Cluster is a calm color block puzzle with an endless arcade run and a ladder of levels. Drag a piece onto the grid and drop it wherever it fits. Nothing falls, there is no time limit, and no move is ever taken from you. The only pressure is the space you have left.

HOW IT PLAYS

Pieces come in a hand of three, and every piece is made of colored cells. Place one so that four or more cells of the same color end up touching, and that whole group clears. Mixed pieces are the interesting ones: one block can finish a red group and start a blue one in the same move.

Clear on two placements in a row and the second is worth double. Three in a row, triple. The chain keeps climbing for as long as you keep clearing, and breaks the moment you make a move that clears nothing. The real game is deciding when to spend a safe placement and when to hold out for the combo.

TWO WAYS TO PLAY

ARCADE: endless. The run ends when none of the three pieces in your hand fits anywhere on the board. Chase your best score, and watch for the New Best! pop-up when you beat it.

LEVELS: every level gives you a target score and a limited number of pieces. Reach the target before you run out and you move on to the next one. The levels start gentle and get tighter as you climb, and you can take back a move with the undo button.

WHAT'S IN IT

- One bomb per arcade run: a 3x3 blast you aim yourself and drop on whichever corner of the mess you want cleared
