Create to-do lists and complete tasks on time to discover new blocks. The longer you stick with a theme, the more chances you'll have to unlock new kinds of blocks. For example, if on the first day of using a theme you complete all the tasks you've scheduled for the day, you'll have a chance to discover two different kinds of blocks. After using the same theme for three days, complete all your tasks on time and you just might unlock a third kind of block, and so on. Please note, even if you don't complete your tasks on time you will still be able to discover new special landmarks.

• "Delayed" tasks affect your land, causing geographic rifts and damaged or unfinished objects, for example damaged cable cars, roads, bridges, tunnels, etc.
• "Canceled" tasks cause cross symbols to appear on your land, for example on the blocks, ditches, soil, etc.
