Tower layout
Time 0:00Pairs 0
Five columns and four levels: 50 tiles. This is the default on a phone because the board sits well on a narrow screen.
No free pairs left

Why phones like it
The board is short and almost square, so on a 375-pixel screen the tiles stay noticeably bigger than in Pyramid or Turtle. Your finger does not cover the row above.
Clearing it
Upper layers hide the middle, so free the top and the sides first. Taking pairs from the left and right columns early usually opens the centre faster.
How long it takes
A calm game runs four to six minutes; experienced players finish in about two and a half.
