Rumbleball, a sponge rubber core ball.

inning clock
The addition of an inning clock raises the stakes and changes how teams strategize and play the game, a major departure from traditional baseball. The inning play clock fuels intensity, it doesn’t just track time — it drives the action given each Rumbleball game an palpable sense of urgency every moment of the game.

dual-scoring system
A dual-scoring system transforms each player on the field into dual-threat capable of hitting, running, dodging, defending, and scoring on both offense and defense.

No baselines
The real game-changer, baserunners are not confined to traditional base paths. Instead, they can move freely within the entire infield, choosing their own sequence of bases creating dynamic, high-stakes perpetual rundowns at every turn.

contact
Rumbleballers are allowed to engage their opponent with legal competitive contact.

the crown
The matches are played on a field known as The Crown, a traditional-sized baseball field where dodging, hitting, and running take center stage.

The Format
The format is simple: the first team to win 2 out of 3 innings takes the match. The first team to win 3 matches wins the game and claims The Crown.
