Cog Evolution: Merge & Battle

Drop a gear on the wheel. Fuse it with its twin. Send the tribe out to fight.

Cog Evolution is a merge game that turns while you play it. Gears drop out of the store onto a wheel that never stops moving, and two matching gears fuse into the next tier up. What you build on the wheel becomes the army that marches out below it — so every placement is really a decision about the fight.

Win the stage and your people move one age forward. Stone spear, bronze, castle, steam, electricity, space.

THE GEAR WHEEL

• Drag gears out of the store and drop them where you want them

• Two matching gears fuse into a stronger one — chain the fusions for a bigger jump

• The store offers three gears at a time, priced in drums

• Not what you need? Refresh rerolls the store for 10 drums

• Press Fight when the wheel is built

EVOLVE YOUR TRIBE

• 12 ages, from the Stone Age to space

• 36 troops — Primitives, Stonehurlers, Archers, War Elephants, Musketeers, Cannoneers and more

• Every troop has 4 forms, so there are 144 fighters to unlock

• Upgrade a troop's attack and health, or evolve it into something else entirely

• Each age also raises your Base HP — the health bar the enemy has to chew through

101 STAGES

• 101 stages, each with its own wave timing, base HP and coin payout

• Your tribe fights automatically below the wheel — you build, they brawl

• 10 bosses stand between you and the end of the road

GEARS THAT CHANGE THE FIGHT

• Multiplier gears raise what the wheel produces

• Troop gears field more fighters

• Coin and Meat gears keep the tribe fed and paid

• Speed, Freeze, Shockwave, Morale, Meteor and Knockback gears each flip a fight

MORE TO DO EACH DAY

• 7-DAYS sign-in with a reward every day

• Mission, Lucky Wheel and Battle Boost

• A dungeon, a gacha and a card collection that unlock as you push forward

• 30 cards span the whole tech tree: Stone Axe, Bronze Mirror, Castle, Steam Locomotive, Light Bulb, Telephone, Airplane, Internet, International Space Station

HOW IT PLAYS

• One finger: pull a gear out of the store and drop it on the wheel

• Watch the fight below the board and collect what it pays out

• Spend coins on troops, on evolving your age, and on Base HP

• Pause any battle if you need to stop

WHY YOU'LL LIKE IT

• A short loop — one merge, one fight, one age closer

• Easy to start, and the wheel gets crowded fast once you're chasing a chain

• Every age changes how your tribe looks on the battlefield

• No account, no sign-up — just open and play

• Plays fully offline

Build the wheel. Send the tribe. Evolve.
