Please swipe between the tiles situated.
Tiles are folded and vanished if one tile matches with counterpart tile.
[Shit can be used instead of shuffle]
After swipe between the tiles, remaining tiles move with reference to cutting line of the said swipe.
This movement is called "shift".
"Shift" movement(s) can be used to generate new pair(s) of tiles that match with counterpart tile.
Have a nice day!
