Welcome to Fissioport A floating harbor in the sky where elemental cards clash on wooden decks. Tap any card to launch a fission attack on its neighbors. Elements follow a restraint cycle where Fire overcomes Wood, Wood overcomes Earth, Earth overcomes Thunder, Thunder overcomes Water, and Water overcomes Fire. When your element dominates, the target shatters and your card upgrades. When two identical elements collide, they fuse into a radiant Pure Card that defeats anything once. Chain Reactions Eliminating a card can trigger cascading reactions across the grid. Build long chains to unleash Fission Storms that sweep entire rows clean. The longer your chain, the higher your score multiplier climbs. Energy System Every tap costs energy. Each successful elimination restores a fraction. Plan your moves carefully to keep the voyage alive as long as possible. Five Voyage Difficulties Calm Seas offers a compact 3x3 grid for quick sessions. Trade Winds expands to 4x3.
