After few times I installed this game this time no Tiger Shark I can use. I bought before and used to stay but no more but other sharks I bought very small, small, medium and large shark sharks still there no matter how many times I installed it. When I was going to buy Tiger Shark back and hope to stay available not have to buy it again then price gone up. Finally I have enough coins to buy it but price of the Tiger Shark gone up again. I uninstalled it now because had enough of it.
