Tips and tricks
- Learn the controls alone for two minutes before you invite a friend. Fumbling the basics is the fastest way to lose a match you should win.
- Use the first round to test. Try something unusual and see how the opponent reacts; the information is worth more than the round.
- Be a good winner. Rematches are how multiplayer games stay fun, and nobody replays a gloater.
- In shared-keyboard games, agree on who uses which keys before you start — hand collisions cause more losses than skill does.
- Because this is a Multiplayer game, expect surprises — real opponents do not follow the patterns bots do.
