The card pile represents the number of cards (objects) that you still need to collect in the level. Every time a new wave is loaded, the amount goes down as cards move from the pile to the ‘board’.
Each goal card can represent 1-99 items of the same kind for you to collect.
Goal cards appear in waves, with each wave able to show up to 5 different items. Once all items have been collected, a new wave appears until there are no more cards to collect.
Collect gems for an extra bonus!
Throughout the game, gems will appear and you can collect them to gain a bonus.
Please note: Collecting gems is optional and the level can be completed even if no gems are collected. When collected, gems appear in the relevant spot in the upper part of the screen.
