Orbit

Number bonds · 30 levels

Spin the rings so every spoke adds up the same.

How to play

1. Tap a ring to turn it one notch clockwise (Shift-tap, or the ↺ button, turns it back). The dark centre ring never moves.
2. Each spoke runs from the middle to the edge. Add the numbers along it: every spoke must equal the target in the centre.
3. Start with one movable ring. Level 3 adds a second, level 9 a third, and level 17 a fourth. From level 24 two rings are geared ⚙: turning the marked one also turns its partner one notch the other way.

Solve one spoke at a time from the inside out. The bubble at the end of each spoke shows its current total.
