# Bullseye

Doubles & trebles · 30 levels

Check out on exactly zero, finishing on a double.

## How to play

- Tap the board to throw. The thin outer ring scores double, the middle ring treble; the centre is 25, the bullseye 50.
- Take the score on the chalkboard down to exactly 0 with the darts you have. The last dart must be a double (the 50 bull counts).
- Go below 0, leave 1, or end on a non-double and it's bust: the darts come back. Some levels close beds or hide a score you can't finish.

Small rings are hard to hit on a phone, so a tap opens a zoomed slice: pick the ring there. Odd scores need a single first to leave an even double.
