This is a continuation from here:
The new pirate kingdom coming soon would be a perfect place to have a betting minigame.
Once very hour there would be 2 completely random teams that the AI then uses to face each other. A player can choose to place a 10,000 gold bet on either team winning the match prior to the match starting. All winners evenly get the losers gold distributed to their mail and their own 10,000 back. The game will queue the random team that comes next during the matchup that is already taking place, so that allows an hour for betting to take place between every match. All bets are final and cannot be changed, with a notification appearing that says so. No betting for a match that is already taking place can be made. A player doesn’t have to watch the match to win/lose the rewards; placing the bet alone each hour is enough.
Winning X amount of bets could even give some kind of additional reward to make it worth doing. Nothing huge, but in the theme of plundering it could be something like a little bit of extra gold, maps, and a few keys.
