Coin Dozer is a free android game by Game Circus which let’s you play on a coin machine and win (fictional) prizes.
Its highly simplistic and sadly deserves its cost considering its crazy use of in app purchases, adverts and that annoying thing where you have to wait a very long time for more coins.
Other than those obvious free-to-play problems it is actually alright. Coin physics work and there are also special coins as well to make it more interesting.
I would of liked a much larger range of prizes though ad maybe different machines too.
Overall its OK for the casual person with no money but there’s a lot more things you could be doing.
