Im playing pokerstars on an IPAD with 'play money'.

From google searches, I can 'top up' my play money 3 times an hour if i run out, by clicking on the 'dealer' & topping up..

However,i cant find the right combination - where to find it on the IPAD. is there a quick tutorial (with pictures ?) as to where to click / go to ?

Ps, I can see, but things are a bit small on the IPAD, so not too clear.

Thank you
