Vice & Versa

The main deck of cards contains 99 cards numbered from 1 to 99
4 special cards (numbered 0 and 100) indicate the starting values of the 2 ascending heaps (0) and the 2 descending heaps (100).
The principle is to discard the main cards on the 4 piles placed at the top of the screen :
- By systematically increasing the value on the 2 ascending heaps.
- By systematically decreasing the value on the 2 descending heaps.

By exception it is possible to put a card with a value exactly 10 less (respectively more) than the card on top of an ascending (respectively descending) pile.

The game is played with a hand of 8 cards and the draw pile is made automatically after 2 moves played per turn (this value can be set between 1 - one card drawn on each move played (easier) - and 4 cards drawn, more difficult).
It is possible to move a card either by tapping on it to select it and then on the destination pile or by dragging it to the chosen pile.

Success is won if you can discard all the cards. Otherwise your score is equal to the number of cards remaining on the deck, including the deck and hand.
The best score is the lowest.
