About Fillblox
An engaging logic puzzle where your goal is to fill the playing field with shapes. You're given several blocks of different forms — drag each one into place so that not a single cell is left empty. Sounds simple? With every level, the board gets larger and the pieces grow more numerous and more intricate. An adaptive difficulty system adjusts to your pace — if you're blazing through levels too quickly, the game will throw a tougher challenge your way. Stuck? Use a hint to automatically place one piece in the right spot.
Expect puzzle at its core, with a streak of thinky woven through the design. Pick it up for a short break or settle in for a while — it runs well on phone, tablet, and desktop alike.
Two quick pointers before you dive deep: If the game has a hint button, save it for when you are genuinely blocked, not just slow. Work from the corners and edges inward — they usually have the fewest possible solutions.
Fillblox is free to play and ready to go on Glaze Games — no app, no account, just tap Play and start.
