Reef Reward Rumble is a play-money gacha battler where you open gift boxes to collect fighters — 🐠 — then send your best team to war. Every box you open reveals a random hero from a roster of 12, graded Common to Legendary, with a satisfying rarity reveal and a confetti burst for the big pulls. Pull duplicates and your fighters level up, growing stronger every copy, so even commons stay useful. Pick up to 4 heroes for your squad, then tap BATTLE to auto-fight an enemy wave: your team's total power, plus a little luck, decides victory. Win and you bank gems and advance to a tougher wave; lose and you regroup with a stronger lineup. Flip on AUTO to let the squad grind waves on its own. Chase the rares — heroes like Lion King and Phoenix Lord can carry your whole team — and push your wave count to a new high score. It is completely free, runs in your browser on phone or desktop and autosaves your collection. Important: this is 100% play-money — gems are earned only by playing, there are no purchases, no real money and no paid loot boxes of any kind. How far into the waves can your collection climb in Reef Reward Rumble?
