Tron

Solar Sailor & Bit – On the grid bugs screen, sometimes a Solar Sailor will appear at the start, sailing across the top of the screen. This can be almost guaranteed to happen if you do the following.... during the Grid Bugs level, don't enter the circle until the timer reaches at least below 18 - this is tricky to do so be careful. It will drop a “bit”, which is worth bonus points if you can grab it!

When you beat 1,000,000 points on Tron, the score rolls over to 0. Also, you don’t get another free guy passing 10,000 again!
