iPod touch Ipod touch game help

Hi guys!

got the ipod touch. Duno what generation it is....think its the latest. Havent had it for very long.

Anyways i went to itunes store and bought 5 games.

Unfortuneatley i can only play 1 of them! (pool)

the others (sudoku, brain game, tetris and texas hold'em) dont work!

please help...ive paid £3.99 for each and its such a waste.

Anything i can do????

Nope they dont require wifi

its the games i listed.....tetris etc.

I went back to the itunes store and it stated above that it only works on ipod nano, 5th generation and all the ones that have those jog thingys. Not sure what you call them.

Is there anyway to exchange these games or something?
since they totally useless to me :/
