Action Bank is a 5 reel, 20 pay line slot that provides lots of action in spite of the absence of complicated bonus rounds. There is a great looking Joker symbol that is wild and a Vault symbol that triggers an initial 5 free spins that you can gamble your way up to 25. Any ‘O’ symbol that drops has the potential to transform in to a Vault symbol. Action bank is certainly a mobile slot game that you may want to spend some time on.
