TriPeaks rejects an exposed card: compare it with the current waste card
A visible card in MobilityWare TriPeaks can be ineligible for the current move. Before treating a tap as an input failure, identify the top card on the waste pile and the rank you tried to play.
Read the setting
MobilityWare describes a one-rank-up or one-rank-down rule. With a seven on the waste pile, check an available six or eight. A nine does not match that seven. A different game with a similar name may use different details.
Compare a specific example
When no card fits, the publisher describes drawing from stock if stock remains. Record the new waste rank before trying the same card again. If the first legal move is also ignored, note whether other parts of the app respond, and capture the board in ordinary solo play for a support report.
