Rumblebots is divided into six rounds, each consisting of two phases: Build and Battle.

In the Build Phase, players assemble new Bots, adding them to your decks.

In the Battle Phase, players compete with other players in auto-battler style clashes to gain precious crystals.

Win the game by being the last one standing in the final Showdown round, or by achieving early victories by having 6 crystals more than each of the other players before Showdown.
