Tower of Babel solitaire is usually used to practice playing cards.
The cards from 2 to 10 of coins are taken, shuffled and divided into three piles of three cards each.

The task is to reach a single pile of 9 cards from 10 to 2, simply by moving any card onto a card of higher worth, without exceeding the 3 columns.

It's difficult and time consuming, but the success rate is 100%.

You have to tap on the card and the tap where you want to put It.

It must be said that if a card lands after the deal on a card of immediately higher worth, this according to the original formulation should be moved, however in my formulation this is not necessary.

The total number of steps you take also counts, and when there is an end-of-game window you can share it on Twitter, start a new game, or exit the program.
