The Aquarium Arcade is a new added option in Happy Aquarium
Click on the Blue Tent and step right up to the arcade!
There is only one game, Make a Match. 16 tries cost 12 pearls, and it's expensive. Some items, like the Green Mini Orca, Orange Mini Walrus, Green seal and many more items can only be purchsed by winning tickets. To get tickets, you must play Make a Match. If you don't match, you get a ticket. 15 Tickets has a diamond, so that's big!
