You start the game with a single panel containing 35 gray tiles, each of which holds a hidden Challenge. You must complete at least one of these secret tasks before you are provided any additional details.
There are three hammers hidden within each Challenge panel. When you complete an appropriate Challenge, a single-use hammer appears near the Touch Screen’s right edge. Hammers can be used to unlock Challenges without performing the corresponding tasks.
When you successfully complete a Challenge, an image appears on the corresponding tile. Select this image on the Touch Screen to review the task you’ve completed and the resulting reward. Additionally, completing a Challenge causes any adjacent tiles to change color. Blue tiles represent revealed (but incomplete) Challenges. If a tile turns light blue, it means that completing the revealed Challenge will grant you a hammer in addition to the standard reward.
Using Hammers
When you use a hammer to open a tile, you gain all the benefits of having completed the corresponding Challenge—you’ll gain any rewards or hammers your selected tile contains and reveal the Challenges on any adjacent tiles. This allows you to bypass particularly difficult Challenges or to gain useful rewards fairly early in the game.
It’s important to note, however, that not all Challenges can be cracked. When you select a hammer, look for any “no symbols” that appear on the Challenge panel. These tiles are impervious to hammers and can only be unlocked by completing the stated Challenges through gameplay.
Each hammer can only be used within its panel of origin. You can’t, for example, use a hammer earned from the first Challenge panel to crack a tile on one of the subsequent panels. This means when you complete a Challenge panel, any unused hammers will go to waste. So, plan accordingly!
