Well the 1 on 1 version of Threefry is not too difficult but if you don't know the basics of coin magic you may have difficulties.
Depending on the size of poker chips (never played poker with chips so I'm clueless on that) it may be hard/impossible to do.
I would reccommend Threefry for beginners in coins, and Hellbound Spellbound for the those who are more advanced and have no trouble with the basics.
