What Is Merge Master: Rainbow Friends

Merge Master: Rainbow Friends is a mobile and web‑based merge‑combat game in which players combine identical “rainbow” monster units to evolve them into stronger forms and deploy them to fight enemy squads. It blends puzzle mechanics (drag and merge) with strategic combat: you must plan which monsters to fuse, position them wisely, and balance your army’s composition. As you progress through levels, enemies grow more challenging, forcing you to think ahead about merges, timing, and resource allocation. The visual style is colorful and engaging, and the controls are generally simple (e.g. drag and drop or finger gestures). The goal is to become powerful enough to defeat waves of foes and unlock higher tiers of monster units. :contentReference[oaicite:0]{index=0}

How to Use (Play) Merge Master: Rainbow Friends

Install or open the game on your device or browser (Android, web, etc.). :contentReference[oaicite:13]{index=13}

If needed, grant permissions or initialize your profile to begin.

Start the first level or tutorial: you’ll be given basic monster units to place.

Place two identical monsters adjacent or drag one onto another to merge them into a stronger version.

Continue merging duplicates as higher levels allow combining same tier units.

Deploy merged monsters to fight the enemy waves; watch the combat unfold and see which units perform best.

Between rounds or levels, you may get rewards (coins, gems, skins) to unlock more units or upgrade stats.

Use unlocked units or skins to diversify your army; swap or replace weaker units if needed.

Keep merging strategically: avoid merging too early, and plan ahead which units you’ll need to reach desired tiers.

Advance to subsequent levels, each with tougher enemies, and repeat: merge, deploy, upgrade, refine your strategy.

If stuck, use boosts, in‑game currency, or wait for cooldowns (if applicable) to continue making merges.

Rinse and repeat: over time, your monster army becomes stronger and more varied.
