The modes
Three modes besides the campaign.
Daily challenge
One board a day, the same for every player, from levels 8 to 29 with the trains reshuffled. It changes at midnight on your phone's clock. Each day you win adds to your Streak; a missed day starts it over. Share sends your result as text. It opens once level 8 is cleared: Clear level 8 to unlock the daily challenge.
Marathon
Deliver as many trains as you can: no clock, no target, three lives, on the board of level 12. The trains roll faster every ten clean deliveries. Your Record is kept. It opens with the daily challenge.
Zen mode
Any unlocked level, with no clock and no lives. Nothing is recorded in zen mode — no stars, no scores.
