GridLock

GridLock is a fresh twist on word puzzles — swap sliding tiles to form crossword-style words across an interlocking grid. It's part crossword, part sliding puzzle, and 100% brain teaser. Easy to pick up, impossible to put down. 🧩 HOW IT WORKS Each level presents you with a scrambled grid of letter tiles. Swap tiles to spell valid words horizontally and vertically — just like a crossword. Sounds simple? Think again. Special tile modifiers add layers of strategy that will keep you thinking moves ahead. 🔒 STRATEGIC TILE MODIFIERS Not every tile plays by the same rules: • Locked Tiles — frozen in place until you complete nearby words • One-Swap Tiles — you get a single move, so make it count • Limited-Swap Tiles — every swap is precious; plan accordingly • Directional Tiles — restricted to horizontal or vertical movement • Adjacent-Only Tiles — can only swap with their immediate neighbors Master the modifiers.
