“5 Card Touch” from Griffin Technology is a very simple game for iPhone and iPod touch that emulates the most basic poker slot machine game — five-card draw. Here’s how it works. You start with $1,000 in virtual funds and place your bet of between $1 and $5. You are dealt five cards, face up. For example, I bet the maximum and received a pair of nines, a pair of fours, and a three. After you receive five cards, you have the option of discarding up to five cards and drawing new cards to replace them.
