Read full description

Singularity is a strategic chain reaction game where every move can trigger a gravitational cascade. Place orbs on the grid, build up critical mass, and watch as explosive chains ripple across the board, but your AI opponent is doing the same. GAMEPLAY • Place orbs in cells to build toward critical mass • When a cell overflows, it explodes into neighboring cells • Chain reactions cascade across the board, capturing enemy orbs • The last player standing wins FEATURES • Multiple AI difficulty levels — from beginner to brutal • Various grid sizes for fresh challenges • Level up and earn XP with every match • Unlock achievements as you master new strategies • Daily login rewards to keep your streak alive • Beautiful dark cosmic visuals with smooth animations STRATEGY RUNS DEEP Easy to learn, difficult to master. Every cell on the grid has a different critical mass. Corners and edges overflow faster — use that to your advantage. Plan your placements, anticipate the AI, and set off the perfect chain reaction to wipe the board. Can you collapse the singularity?
