Merge Rush Attack

Merge Rush Attack is a fast tap-and-merge runner: spawn a crowd, fuse units into stronger tiers, and smash through boss walls before overheating. A portrait clicker with escalating walls, paid merge chains, and risk–reward tap pressure that turns every sprint into a short, tense power race.

Build a strong enough crowd to break the wall at the end of each run. If your squad’s power is equal to or higher than the wall’s HP, you win the level and earn coins. If not, the run fails and you can retry (or watch an ad for a soft boost).

The crowd runs forward automatically.

Tap/click the screen to spawn more units.

Merge 3 identical units into 1 stronger tier (unlock merge and upgrades in the Shop with coins).

Reach the wall and compare your power vs its HP.

Spend coins between runs to unlock higher merges, auto-merge, and power upgrades. From level 5, manage overheat — tapping too fast fills the heat bar and can weaken your squad.

Controls:

Tap / Left click — spawn units

Merge button — merge 3 matching units (when available)

Shop button — open upgrades

Overheat Shop — buy heat defenses or claim crystal rewards

No keyboard movement — the squad runs on its own; the game is designed for touch and mouse click
