Blitz 90s
Ninety seconds. Full pace. Type as many zombie words as you can before time runs out, then drive through the gates of a fortified safe zone with a small town behind them.
Why it works
Blitz is quick, so it is easy to fit into a break. It is a good way to test your speed and accuracy, and it keeps its own board of best scores so you can beat yourself run after run.
Tips
Keep your combo going, because every zombie that reaches the truck resets it and time is short. Use power-ups early, and watch for the boss halfway through.
