About this game

Get ready for a fresh and satisfying puzzle challenge! In U Block Jam, your goal is simple: clear U-shaped blocks, match their colors, and fill the boxes waiting on the conveyor belt. But there’s a twist — only the first box in the queue can be filled. Once it’s complete, it moves away and the next one slides forward.

Plan your moves carefully:
-Break U-shaped blocks into colorful pieces
-Match them with the active box in the queue
-Use slots wisely to store and manage blocks
-Unlock the next box only when the current one is filled

Each level is designed to be fun, tricky, and deeply satisfying. You’ll need to think ahead, balance your choices, and enjoy the rewarding feeling of completing every sequence.
