How do I reach level 81?

When the game says "decorate," it means you need flower value to reach the next level and you don't have enough in storage to make up the difference. Next to your picture profile/avatar game will show you how many more flowers you need. Flowers can be obtained from buying decoration, renovating landmarks, upgrading buildings, and sending Jack on missions for flowers/decoration. If you choose to buy decoration, you must wait for construction to finish and remove the red ribbon before the flower value will count. Adding flower value to your island will make the counter count down until it reaches 0, at which time you will level up, the corresponding scene will be available, and then the counter will show how many more flowers you need for the next level. Any extra flowers will go toward achieving the next level.

If you need coins, replay mastered scenes to earn them. If you choose a scene you enjoy, you will likely score higher and get more coins (1 base coin for every 10,000 points). Earn extra 10 coins for "perfect" scores, which just means no hints, no misses, and no lapse of the bonus bar. To get higher scores, find objects in the order they are written (left, middle, right, repeat) and read 2 or 3 words at a time.
