De-stress yourself with this unusual and absorbing game.

Your challenge is to achieve the highest score by keeping all the colours of quarks in balance for as long as possible as they bounce around the screen and collide. Each collision causes the quarks to change colour, and the fastest quark always wins. Eventually the slowest will become extinct leading to all but one colour.

Hold out as long as you can by carefully speeding some of the quarks up - but be warned (!) doing increases the chaos and makes the game harder to control and predict.

Careful judgement is essential and only calmest under pressure and most Zen-like will triumph!
