Merge colorful pals, grow weird combos, and survive the night in this addictive merge-idle hybrid. Smash identical friends together to unlock stronger allies, feed them snacks, build a safe base, and beat spooky waves all wrapped in neon-candy visuals and frantic, joyful chaos.

Merge Rainbow Friends is a fast-paced merge-and-defense game with a cute-but-creepy vibe. You start with tiny color sprites that wander your camp. Merge two identical sprites to create more powerful versions with unique abilities. As your roster grows, so do the attacks from shadowy Nightlings defend your base, craft upgrades, and unlock bizarre team synergies to push deeper into nightly waves. Short sessions, huge payoff, and tons of surprising combos perfect for quick plays or marathon grinding.

• Camp upgrades: Expand the base: more slots, faster merges, better resource yield, and cosmetic decorations.
• Mini-bosses & events: Special nights bring enormous foes or map modifiers: foggy nights, mirror realms, double-merge boosts.
• Achievements & secrets: Discover hidden merges and Easter eggs for permanent perks.
