Block Stack is one of the most classic puzzle games. Pieces of various shapes (I, O, T, S, Z, J, and L) are constantly falling from the top of the screen. Players need to control the left and right movement and rotation of the squares to make the squares stack at the bottom. When a row is completely filled, the row is eliminated and scored.
Game operations: The left and right direction keys move the box, the up direction keys or specific buttons rotate the box, the down direction keys accelerate the fall, and the space bar drops directly to the bottom. As the score increases, the speed at which the cube falls will become faster and faster, testing the player's reaction speed and spatial planning ability.
Elimination rules: Eliminate 1 row at a time, score 100 points, 2 rows 300 points, 3 rows 500 points, and 4 rows (Block Stack) 1000 points. The game ends when the block pile reaches the top and cannot accommodate new blocks. Use Canvas to draw game graphics, and JavaScript handles game logic and collision detection.
