About this game

CalCube is a number puzzle and math brain game. Drag across neighbouring tiles so their sum hits the target exactly, using the right number of tiles. Simple at first, then every tile starts to matter.

HOW IT PLAYS
You get three hearts per level: a wrong answer costs a heart, and if you run out you get a fresh board to try again. From level 4 an hourglass adds a little pressure. Need a nudge? Hints show you one tile of the solution. Stone tiles block the way, gold tiles count double, locked tiles open when a neighbour clears, and later chapters limit your moves. Every level is verified solvable.

BUILT FOR THE LONG RUN
• 100 chapters and 2000 levels with a slow, steady climb
• A fresh daily puzzle with a streak to protect
• Three stars to earn on every level, and accent colours to unlock
• Dark mode by default, light mode if you prefer
• A one-handed layout designed for phones

The game contains ads. A one-time Remove Ads purchase is available.
