About Cuppadoku

Cuppadoku is a hot-drink logic puzzle in the Star Battle family. Place one drink in every row, every column and every coloured region, with the rule that no two drinks may touch, not even diagonally. The regions are irregular shapes, so the puzzle is solved by working out which cells are forced and which are impossible.

It is quick to learn and a proper stretch on the harder grids. A new puzzle every morning, free in your browser, with a leaderboard for the daily solve.

How to play Cuppadoku

  1. Tap a cell to place a drink. Tap again to mark it as empty, and once more to clear.
  2. Every row, column and colour region must contain exactly one drink.
  3. Drinks can never be adjacent, including diagonally.
  4. Fill the grid so every rule is satisfied to finish.

Questions about Cuppadoku

Is Cuppadoku the same as Queens or Star Battle?
It is the same one-per-row, column and region rule with the no-touching condition. Cuppa's version uses drinks instead of stars or queens.
Do I need to guess?
No. Every puzzle is solvable by logic alone.
How big are the grids?
From five by five up to eight by eight. Larger grids offer more of a challenge.
