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.
Sometime between 2025-09-24 and 2026-05-14 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.
