Shape Stack
Tetris-inspired with a modern twist.
About Shape Stack
Shape Stack is MOJGAMES’ take on the all-time-classic falling-block puzzle. Seven block shapes drop one at a time from the top — slide them left and right, rotate them to fit, and complete a full horizontal row to clear it and score. Clearing several rows at once is worth far more, so it pays to set up a deep well and drop a long piece in for a big multi-line clear. A ghost outline shows where the current piece will land and a preview shows what is coming next, so you can plan ahead. The longer you last the faster the pieces fall — it ends when the stack reaches the top. Free, instant, and playable with touch or keyboard.
Frequently asked questions
How do I play Shape Stack?+
Pieces fall from the top. Move and rotate them to complete full horizontal rows, which clear and score. On touch: drag to move, tap to rotate, swipe down to drop. On desktop: arrow keys to move, up to rotate, space to hard-drop.
How do I score the most points?+
Clearing multiple rows with a single piece scores far more than clearing them one at a time — and clearing four rows at once is the biggest single play. Points also scale with your level.
When does the game end?+
The game ends when the stack of pieces reaches the top of the board and a new piece can no longer fit.
Is Shape Stack free and mobile-friendly?+
Yes — it is free with no download or sign-up, and supports both touch gestures and keyboard controls.
