Centibox Numbers 100

Can you fill every cell?

CENTIBOX is a deceptively simple number puzzle that will challenge your brain like no other. Place tiles 1 through 100 on a 10×10 grid — but each move must jump exactly 3 cells straight (horizontally or vertically) or exactly 2 cells diagonally. One rule. 100 cells. Infinite challenge.


THE ULTIMATE BRAIN TEASER

Inspired by the legendary Knight's Tour chess problem, Centibox is pure spatial reasoning distilled into a single grid. Every move matters. Plan ahead or get cornered — the puzzle punishes careless play and rewards sharp minds.
