Suggestions are a guided way to play the game, where you can earn rewards for completed the suggested puzzles or activities.
Tap 'Suggestions' from the navigation bar at the bottom of the game screen to open the Suggestions Menu. From here you can select an item to be automatically taken to that puzzle's location in the game.
Completing suggestions fills in segments of the Prize Wheel – when all the segments are filled, a Bonus Card is awarded.
Bonus Cards bestow rewards (e.g., coins, tokens or keys) that can be claimed once per card, or time-limited bonus effects. Awarded cards are stored in the 'Cards' section of the Journal - or you can tap the 'Cards' button on the Suggestions screen to go there quickly.
