There are total of eight bugs in the game. Player starts with a beetle, the weakest bug, but can be upgraded to a faster and a higher performance bugs. To do this, races must be won and earnings collected. Bugs are won and earned in this order: beetle (given), ladybug, cockroach, grasshopper, hornet, praying mantis, scorpion, and blackwidow. When starting with weaker bugs, one must use tactics or strategies to win the races. The latter four are fast, have better performance wheels, and tougher armor. Once you acquire one of those, it's matter of seeing how many kills you can get and how fast you can finish the race.
