How to play
Use eight on/off switches to build a target decimal number in binary. Each lit switch contributes its labeled power of two.
- Toggle the 128, 64, 32, 16, 8, 4, 2 and 1 switches, then check the total.
- Build 10 targets within 3 minutes. An incorrect check costs a point and keeps the same target.
- Your best stays on this device. Share a seeded challenge with a friend; a solved run beats an unfinished run, then points and time decide.
