Product summary
Review the store description, core capabilities, and common use cases.
Rubus is a bite-sized logic puzzle that lives in your browser toolbar — no installation fuss, no accounts, no ads.
─── HOW TO PLAY ───
Every cell holds a value from 0 to 3. Tap a cell and it — along with its neighbours — counts down by one. Values wrap: 0 goes back to 3. Clear the entire grid to zero to win.
That's all the rules. The depth comes from figuring out which cells to tap, in what order, to unravel the puzzle without creating new problems elsewhere.
─── TWO MODES ───
Human mode — tapping a cell affects the cell plus its four orthogonal neighbours. Tight, local, surgical.
