Charge the battery past 100%. Tap fast and watch the number grow — 500%, 9,000%, a million% — while funny battery faces go wild. Battery Overcharge is a one-thumb game about holding on for a little bit longer than feels safe.
Hold to Charge, Let Go to Cool
Plug in the cable and hold. The number climbs while the battery heats up. Every order asks for a charge inside a target window: let go inside the window and the order is filled, let go too soon and the charge drains away, hold on too long and it pops. Two slips are forgiven. The third one bursts.
Funny Battery Faces
Empty batteries look sad and cry. Full batteries smile. Overcharged batteries puff up, wobble and go silly. The more you charge, the funnier they get.
Numbers That Get Silly Large
The first battery wants 250%. Later ones want 9,000%, then 90,000%, then numbers so long they stretch right across the screen.
Push Your Luck
Just past the window sit six Overcharge notches, paying x1.5 up to x12 Volts. Every notch you climb into might pop the battery. Bank a safe delivery, or hold on one moment longer for a much bigger payout. That choice is the whole game.
Collect New Batteries
Every battery has its own temper. Some run hot and give you barely a second. Some drain the moment you let go. Fill orders to earn Volts, then spend them in the Charger Shop on new battery friends and new rigs to charge them on.
Easy for Little Hands
One thumb, and that is it. Every button is a picture, so no reading is needed. A round runs about twelve seconds. There is no energy to wait for and no daily streak to protect. Sound, music and vibration can each be turned off, and reduced motion and high contrast options are built in.
Plays Offline, No Ads
The whole game works with no connection. There are no accounts, no sign-in, and nothing is uploaded. There is no advertising of any kind. The game is free and playable start to finish without paying — Volts can also be bought, and they only ever buy cosmetic batteries and chargers.
A note for grown-ups: the batteries in this game are cartoon characters with big silly faces. Real batteries and real phones should never be overcharged — that only happens in the funny world of Battery Overcharge.
