Don't move the blocks. Change the rules that move them. In SHIFTBOUND, every color follows a single rule: slide this way. Turn a rule tile, and every block of that color slides at once until something stops it. Blocks push, follow and chain into each other. Your goal is to guide every star block out through its matching exit in as few moves as possible. It takes seconds to learn and much longer to master. HOW IT PLAYS • Tap a rule tile to turn it 90°. Every block of that color moves. • Blocks move together, one cell at a time. When the block ahead leaves, the one behind follows. • Get every star block out of its matching exit to clear the level. • Beat the target number of moves to earn up to three stars.• Send two or more blocks out in one move for a chain bonus star. 60 HANDMADE LEVELS Six worlds, each adding a new idea and folding it into everything before: • First Shift: turn a rule, watch them slide • Spectrum: three colors pulling three ways• Lock & Swap: locked tiles that won't turn, and swap tokens that trade two directions • Chain Works: two star blocks on one board, and every move counts • Violet Peak: four colors and a long climb • Pressure Point: plates that hold gates open, as long as something stands on them A solver checks every level, so every puzzle has an answer.
