About Body Evolution
Body Evolution is a 3D runner game about getting fit on the move. Your runner sets off along a track lined with gates, food and obstacles: green gates and fruit take kilos off, red gates and junk food pile them on, and your body changes as you go. Six body stages, from Couch Potato and Heavy through Casual and Fit to Athlete and Superstar, each have their own outfit and look, and the fittest stages leave a trail of stars or flames behind them.
Walls and purple weight doors stand across the track, each marked with the heaviest weight that gets through. After the first three hand-made tracks every level is generated from its number, so the game keeps going with longer tracks and new ideas every few levels: fruit lines, weight doors, shuffling gates that swap sides, treadmills that burn weight and buffet lanes that add it, and food slaloms. Every fifth level ends in a Fitness Contest in front of a crowd. The world changes every three levels, from meadow and beach to city, autumn farm, desert, sunset boulevard, snowy peaks and a starry night city.
The fitter you are at the finish, the more coins you earn: Fit pays 1.3 times, Athlete 1.6 times and Superstar twice as much. The start screen shows which body stages you have reached. Coins unlock eight outfit colours and two upgrades, Fit Start and Diet Boost, and you can slim down once per level to carry on after a crash. Body Evolution works on phones, tablets and computers with no download.

How to play Body Evolution
- Tap Start. Your runner sets off along the track on its own.
- Drag left and right to steer through green gates and fruit, and around red gates and junk food.
- Check the limit on each wall and door: if you weigh more, you crash and the run ends.
- Run on treadmills to burn weight and avoid the buffet lanes.
- Reach the finish as fit as you can: fitter stages pay more coins.
Controls
- Computer
- Hold the left mouse button and drag left or right to steer.
- Phone and tablet
- Touch the screen and slide your finger left or right to steer.
Tips
- Steer early: your runner turns rather than sliding sideways, so line up the next gate before you reach it.
- Read the MAX number on doors before you choose a gate: doors in later levels are stricter than walls.
- Shuffling gates swap sides about once a second, so commit at the last moment.
- Reaching Fit or better at the finish multiplies the level's coins, and Superstar doubles them.
- Fit Start and Diet Boost both help you reach the high stages sooner.
