I am not sure if its the right forum, but today i had a few games on hawai island against a friend, but i dont know how to play that again. The ordinary island is getting more boring every day...

Think u have to buy Hawai battle theme first, it cost 12800 coins, then when click on battle, chose Hawai on theme select screen.
Otherwise, u can go random and hope to bump on someone who have Hawai theme, which is pretty rare atm :)

yep, but it doesn't work everytime. Maybe it's a bug, or it also depends on the other player ("Random" option or something).

should 100% work for friend invites though

Hey guys,
even if you select Hawaii when starting a Random Battle, there is a chance the opposite player has selected either Medieval or Random, to make it fair the theme is selected at random based upon both players choices.

For example:

So if both players select Hawaii theme, the game will select Hawaii. If a player selects Hawaii and the other selects Medieval, it will pick one of the two at random.
