What are Bonus Games?
Bonus rounds or features are mini-games within online slots, commonly triggered by hitting a selection of symbols (typically three scatter symbols, or a pair or more of other symbols), and bonuses can also be triggered at random. The different types of bonus games and features in slot machines are:
- Free spins - You'll receive a number of free spins at your current stake where you keep any winnings and can’t lose any money during the bonus.
- Re-spins - Receive an extra spin at your current stake for free, often with symbols held in place.
- Pick-me - Also called a picking bonus, this enables you to play an interactive mini-game and win instant prizes by picking from random themed selections.
- Instant win - Get an instant cash prize.
- Added/extra wilds - New or extra wild symbols may be added to the reels to help you form more winning combinations.
- Pathway game - Progress through a series of mini-games and win bigger prizes as you go along. It can often be part of a progressive jackpot game.
What Makes a Good Bonus Game?
Because bonus game slots are some of the most popular in the gaming world, the best online casinos will offer a diverse selection of slot machines with bonus games – often hundreds! So, how do you sort the good from the bad? The three most important factors to look out for are:
- Hit frequency - An online slot game could have the best bonus game in the world, but if you can only play it once every 50,000 spins it isn't very accessible! The best online slots have bonus games that are triggered frequently.
- Payout potential - A bonus slot game may come up often, but it might only double your prize. The best online slot bonus games and features will multiply your bet by a considerable amount.
- Fun factor - besides the money, one big reason that online slot machines have bonus games is to make the game more fun. If a bonus game or feature isn’t exciting or fun to play, it might as well not have one. A boring game is a bad game, after all!
Are Bonus Game Slots Better than Regular Slots?
Some online slots don't have any bonus games at all. This is often the case for classic slots, which emulate one-armed bandits and keep things simple and stripped-down. For other slot games that don’t have bonus games and features, it can be because they offer a high chance of winning without a bonus.
At OnlineSlots.com, we think bonus games add to the excitement of playing slots, and often bonus rounds offer the chance of hitting the jackpot. With all that considered, it’s no surprise that many of the world's most popular online slots feature one or more bonus games or bonus features.
