Potion Maker of Darkness
The objective of the game is to create the Potion of Darkness or Potion of Fire.
Swipe the screen up, down, left, or right to move all number potions in that direction. Each potion moves in that direction until it hits the wall or another potion.
Each time you make a move, a new potion appears in an empty spot in a row or column that was moved last move.
