# Learn cubes in three minutes

First light is an interactive tutorial on real boards. Every rule is enforced for real, and when a move doesn't work a hand-written note points at exactly what went wrong.

## The chapters

1. **Your Core.** Place your first shard so it touches your Core at a corner.
2. **Corners only.** Grow your light, and see why sides are off limits.
3. **Get in their way.** Take the gap an opponent needs before they do.
4. **Nodes and surges.** Collect charge, then Leap over a wall and Spark into a gap.
5. **Shatter.** Break an enemy cell to open a path.
6. **Fog.** See only what is near your light, misfire once on purpose, then Scan.
7. **Up a dimension.** Climb onto an opponent's tower in 3D and crown a column.
8. **Graduation.** A short real game against the Ember bot.
