Oases
Shade water so every oasis can reach the number of other oases shown.
Controls
Shade cells black. Black cells may not share an edge, and all white cells must stay connected. Every 2×2 block needs at least one black cell. A circled number counts the other circled cells reachable through white cells without passing through another circle. Tap a cell to cycle black, white and empty.
