THE CASTLE IS YOUR WEAPON

THEY WANT YOUR THRONE.
GIVE THEM HELL.

Your castle is under siege, but its walls hide something unusual: every trap room can move. Rearrange the castle around your enemies, unleash deadly combinations, and survive five waves of increasingly dangerous invaders.

SWAP ROOMS • TRIGGER TRAPS • SURVIVE

A CASTLE THAT FIGHTS BACK

Why build defenses when you can move the entire battlefield?

In Keep Shift, you control four magical trap chambers inside a besieged castle. Swap their positions to ambush enemies, set up combinations, and stop invaders before they reach your throne.

Every room has its own ability and cooldown. The trick isn't just knowing which trap to use. It's knowing when and where to move it.

FOUR ROOMS. ENDLESS TROUBLE.

01 / FIRE

THE INFERNO

Set your enemies ablaze. Burn damage continues even after they leave the room.

02 / FROST

THE FREEZER

Stop enemies in their tracks. Freeze an entire group and create an opening for your next trap.

03 / SPIKES

THE CRUSHER

A brutal burst of area damage. Time your swaps to catch as many invaders as possible.

04 / ARROWS

THE BARRAGE

Target the enemy closest to your throne with a powerful volley of arrows.

SHIFT. STRIKE. REPEAT.

01

WATCH THE SIEGE

Invaders enter from the bottom and climb toward your throne. Keep an eye on their positions and your available traps.

02

SWAP YOUR ROOMS

Drag one trap chamber onto another to exchange their positions. Alternatively, tap one room and then another.

03

TIME YOUR ATTACKS

Every room has a cooldown. Catch enemies inside your traps and combine their effects for maximum damage.

Survive five waves, choose upgrades between attacks, and stop the final boss before your throne is destroyed.
