DisponibleColour logic puzzle · iPhone, iOS 17+
Pure deduction, never a guess.
Every grid hides a secret colouring. The clues are always enough to find it — one coffee, one grid, and let logic do the talking. 300 grids generated and verified by a logic engine: every solution is unique, and always reachable without guessing.
The rule
Counters, signs, one single solution
Counters tally the colours, the = and ≠ signs link neighbouring cells. Everything else is deduced.
The counters
They tell you how many cells carry each colour.
The = and ≠ signs
They link two neighbours: same colour, or different colours.
A unique solution
A logic engine checked every grid: only one colouring is possible.
