Marathon
Marathon has no clock and no target. You have three lives, and the trains keep coming. Every ten clean deliveries, they roll a little faster.
Your record is the number of trains delivered; the home screen shows it. The marathon opens with the daily challenge, once level 8 is cleared.
Zen mode
Zen mode lets you replay any level you have unlocked, with no clock and no lives. Finish the board and you win.
Nothing is recorded in zen mode: no stars, no scores. No full-screen ad either.
Which one to pick
- To beat a number: the marathon.
- To learn a hard board, or just watch the trains: zen mode.
