Block TrioClear

I. Core Game Objective​ Within the fixed 10×10 grid board, you receive 3 random Tetrominoes each round and must place all 3 successfully on the board (no overlapping or going out of bounds). Trigger the elimination mechanism by arranging the blocks to form complete horizontal or vertical lines (10 full grids), which will clear the line and award points. The core objective is to survive continuously and accumulate the highest possible score.​ II. Basic Gameplay Steps​ Receive Blocks: Each round, the system randomly generates 3 Tetrominoes of different shapes (7 classic shapes: I, O, T, L, J, S, Z; each shape has multiple rotation forms), displayed in the placement area below the board.​ Operate Blocks:​ Drag: Long-press the block with the mouse and drag it to any empty space on the board.​ Complete the Round: You must place all 3 blocks of the current round on the board to proceed to the next round. If any 1 block cannot find a valid placement (no empty space, overlapping, or exceeding the 10×10 boundary), the game ends immediately.​ III. Elimination Rules & Scoring​ Elimination Trigger Condition: After placing a block, if any horizontal row (10 grids) or vertical column (10 grids) on the board is completely filled with blocks (no gaps), the line will be eliminated immediately.
