Thanks! In the combo stage, just choose passive cards in your hand (up to 5 per turn), the effects of the cards you chose will be applied in the next turn

Example: you choose a multiplier (multiplies your score) and a hourglass (increases the time to memorize), both of these effects will be applied in the next turn
if you add more cards of the same type to your combo, their effect will be added on top of each other, so you can get really absurd effects (like multiplying your score dozens of times)
its a good strategy to try accumulating cards to combine them so you can get the highest rewards
