'''Beta Block Sumo''' (BBS, displayed in-game as "Sumo duels") is a lives-based free-for-all where kills grant escalating powerup tiers. Each player starts with 3 lives; extra lives are granted at certain powerup levels.

== XP ==

From 2023 through at least September 2025 the mode paid exactly the [[Duels]] formula, with one twist: players queue in pairs, and the +30 win bonus is credited if you '''or your queue partner''' is the last one standing, regardless of your own elimination order. Combat is still full free-for-all (partners can hit each other); only the win crediting follows the pair.

In late 2025 or early 2026 the formula changed, unannounced, to a per-second accrual model: XP grows at about 0.42 per second (with roughly +5 for a win at 0 kills), and kills are worth far more than before (about 30 to 40 XP each in long games). The exact current formula is unresolved.
