12-12! is a clean and addictive block puzzle game that challenges your spatial planning and pattern recognition. The goal is simple: drag colored blocks from the queue onto the grid, arrange them to complete full rows or columns, and earn points. Completed lines clear from the board and free up space so you can keep placing pieces. The game ends when you can no longer place any block.
Gameplay centers on shape management and looking ahead. Pieces come in a variety of fixed shapes and sizes, so you must plan placements to avoid isolated gaps. Clearing multiple lines in sequence scores bigger combos. Because there are no timers, 12-12! rewards careful thinking and long-term strategy. It is ideal for quick plays or longer sessions where you chase a new high score.
