How to play
- Goal
- Shade isolated cells so every numbered well reaches its stated count through empty pale cells, while the pale ground stays connected and has no solid 2×2 patch.
- How it ends
- A chart clears when every well and every ground rule agrees; there is no loss.
- Record
- Only the fastest first solve of each chart is kept; replays are practice.
- Place night stones so no two share an edge. They may meet at corners. All remaining pale ground, including wells, must stay connected, and each 2×2 patch needs at least one stone.
- A numbered well counts each other well it can reach through orthogonal paths of empty pale squares. Routes may turn. Another well is an endpoint: a path cannot pass through it. Several routes to one well count once. The worked picture shows the top well reaching the middle well through a turn, while that middle well blocks the lower well.
- Tap a free square to place a stone; tap again to clear it. Pale notes are optional. Tap a well to highlight its currently open paths and reached wells. Undo, Redo and Restart let you revise a chart; Restart keeps the first clock running. A chart clears as soon as every ground and well rule agrees. Replays are practice.

About Oasis
At a moonlit caravan oasis, brass wells name how many other wells their pale paths can reach. Place separate obsidian night stones to shape the routes.
Explore 160 original small charts across four open shelves. An independent exact counter proves that every chart has one legal stone pattern.
Your first solve time stays in this browser. An uninterrupted first finish may claim the named best beside the clock and on its chart card.
