Some slots with bonuses will actually have the bonus game trigger at random, adding a little spice to the game. These can be found both on free online slots and paid slots.

What Makes The Best Slot Bonuses?

Online slots with bonus features are some of the most popular and widely played casino games, so online casinos will often offer a huge range of slots with bonus games – frequently in the hundreds!

But how do you ascertain what actually makes good casino bonus games? Well, here are the things we suggest you look for in slot machines with a bonus game when playing online:

Frequency of triggering: You could take the absolute best slot game on the planet, with the absolute greatest bonus game around… but if you can only get it in one out of every 60,000 spins – then you're out of luck! This is what we mean we talk about trigger rate – you want to be playing on online slot games with bonus features you can hit frequently.

Potential payout: Now we get to the payout of a slot game bonus. A bonus may just give you double the winnings, where as the best bonus rounds will multiply your winnings by a huge amount and give you the chance to win real money- like a progressive jackpot!

The Entertainment factor: One of the main reasons slots even include these games is for the fun factor. The bonus rounds & bonus features add a bit of fun to the game, change up the pace and often have a strong tie in to the theme of the slot itself.
