In the top right-hand corner of the game playing screen, there's a section to give a current readout - you can choose between various options for what you'd like to see by tapping in the top-right corner.

By default, it shows the current time of day:

Tap once and it will show the number of potential moves you can make:

Tap again to see your current time elapsed in this game (useful if you are trying to beat a friend's time!)

Once again to see the number of shuffles you have remaining:

Finally, tap again, and it will rotate back to the current time:

We have noticed that on some devices, tapping in the corner may not be so easily detected, as the touch sensors tend to be least accurate at the edges, so you may have to experiment with where in that area gives you the most reliable tap detection!
