The Modern Tarot predicts your past, current and future. There are 50 cards that are split on half and randomly spread over 25 squares. You should find the matching halves and position them next to each other by rotating cards, just tap on the card. As soon as a match found, you will get the prediction.
You may try to click on Hint button that will rotate a card with a match, but then some predictions may not come true...
Good luck!
