FloodCube

A daily 3D flood-fill puzzle. Where a flat flood game gives you one grid, FloodCube wraps the puzzle around a cube you rotate, so a colour you spread on one face keeps spreading around the corners into faces you cannot currently see.

Thinking around corners

The board is a cube of six faces - 384 cells at the starting 8x8x6 size. Choosing a colour floods every cell connected to your region, and connectivity runs over the cube's edges, not just within a face. Planning a move means rotating to check what a spread will reach on the far side before you commit it.

A move budget, not a timer

Each puzzle carries a move budget derived from its size and colour count rather than an arbitrary limit, so a solution always exists and the challenge is finding it efficiently. Difficulty scales both dimensions together: the grid grows and so does the number of colours in play, which widens the branching factor at every step.

Daily, Challenge, Infinite and Power

Everyone gets the same daily puzzle, so scores are comparable and a completed run posts to the leaderboard. Challenge mode ramps difficulty in sequence, Infinite keeps generating boards for as long as you want to keep playing, and Power adds its own twist for players who have exhausted the standard rules. Opt into a reminder and you get a nudge when the next daily is up.
