MOBL now has two ways to play: Classic and Relay. The new Relay mode adds a different challenge to the game: one color prepares the ground, and another completes the capture.
A cell cooled by blue balls needs a green ball to capture it. Green cells need red, and red cells need blue. Progress comes from coordinating the populations, preparing territory, and switching laws when the field is ready for the next step.
Paint helps rebalance the two colors you select by turning matching collisions toward the smaller population. Breed, Paint, and Destroy also work over captured territory, keeping population management useful as the field fills up. The goal remains the same: capture all 900 cells while keeping every color alive.
Classic preserves the original rules and remains the default. Choose your mode before starting a new game; each mode has its own leaderboard. Both retain MOBL’s deterministic simulation and its central idea: change the laws, then watch the world respond.
