While waiting for the next bingo game to start, or even while enjoying a game of bingo, it is possible to have even more fun trying Winner Bingo’s slot side games. That’s why each week they offer a £5 free bonus to players of the slot of the week.

This week the chosen game is Rainbow Riches and all players have to do to claim the bonus is bet £10 on the game using the code ‘RAINBOW’.  After doing so a £5 bonus will automatically be credited to your account and you can play even more.

Rainbow Riches is a 5 reel, 20 payline game built upon the theme of leprechauns. On the reels players will find a wishing well, a pot of gold under a rainbow, a gold coin wild and of course a leprechaun.

The slot has a number of bonus features. Landing three leprechauns on the reels triggers the Road to Riches bonus. Players spin a wheel to progress along the road and collect multipliers on the way. There is also a wishing well bonus which awards a cash prize and a Pots of Gold bonus where players need to pick from pots to receive further cash bonuses.
