Made for a coffee break
Logic, never luck
Every grid has exactly one solution, checked by a solver before it ships. You can always reason your way to the end.
Open and play
No download, no sign-up, no waiting. The grid loads in a second on any phone, tablet or computer.
A few minutes, not an hour
Most grids take just a few minutes. Long enough to feel sharper, short enough for a coffee break.
Your progress stays
