Every set of three blocks you are dealt can be placed. We check before we deal it.

BlockSlay is an 8x8 block puzzle built on one promise: the game will never hand you a set you cannot use. Before any three pieces reach your tray, the game verifies that all three fit your board in some order. If they do not, the set is thrown away and another is drawn.

No hidden difficulty. No punishment for playing well.

WHAT MAKES IT DIFFERENT

Most block puzzles quietly tighten the screws once you start doing well, then hand you an impossible set and offer to sell you a way out. BlockSlay does not. The piece weights are published inside the app, on a screen called Fair Deal, along with the exact difficulty curve and the random seed your current game was dealt from. Nothing is hidden.

Difficulty changes with your score, and only with your score. It does not change because you are winning, because you have played for a long time, or because you have not spent any money.

HOW IT PLAYS

Drag pieces onto the 8x8 board. Fill a full row or column and it clears. Clear more than one at a time for a combo, keep clearing on consecutive moves for a streak, and empty the board completely for a clean sweep bonus.

Three modes:
- Classic, with one undo and one second chance per game
- Classic Pure, with neither, for a cleaner score
- Daily Puzzle, the same board for everyone, one attempt per day
