Spring Kings

Read full description

Spring Kings is a fast, physics-driven 1v1 castle-vs-castle battler where balance is everything and every launch can decide the match.
 Build your wobbling fortress on a giant spring, stack Tetris-style pieces to stabilize it, and then fling your entire castle to knock your opponent into ruin. Why you’ll love it - Real-time 1v1 matches focused on quick thinking and creative physics play. - Dynamic spring-mounted castles that tilt, sway, and react to every piece you place. - Build your loadout by choosing up to four structural or offensive pieces with unique behaviours. - Deep upgrades that improve stability, spring power, and special piece effects. - Ranked progression across increasingly challenging arenas with new hazards and layouts. - A workshop system that rewards upgrading your spring, castle core, and piece library. - Multiple viable strategies, from precision balancing to all-in power launches. Core gameplay - Place structural pieces (inspired by Tetris shapes) to stabilize your castle on the spring. - Charge and launch your wobbly stronghold toward the enemy to deal damage or disrupt their balance. - React to shifting weight, momentum, and spring tension as the battlefield changes. - Win by destroying the enemy’s castle core or knocking their structure completely off balance. Meta & progression - Upgrade your structural and offensive pieces to unlock new mechanics and higher impact. - Improve castle parts and spring strength to create specialized builds. - Climb competitive ladders, unlock new arenas, and discover new ways to out-balance and out-launch opponents. - Build smart, balance precisely, and master the perfect spring-powered strike.
