About Funsize Fireworks

Funsize Fireworks is set on an old-school 3-reel, 1-row set of reels that are sure to instil pangs of nostalgia into the hearts of players, as the traditional cabinet-style appearance throws it back to the days of land-based fruit slots. Realistic Games have transformed this much-loved traditional layout into an explosive online casino game. If you love a classic slot machine and the modern technological additions presented in online slots, then this could be a great game for you.

Realistic Games has formed an unmatchable reputation when it comes to creating fruit slot style casino games, by creating slots which add some diversity to a saturated market of pub fruit style reels, so players get a little something extra out of their casino experience. Another of their slots, Funky Spin, is also designed to mimic the age-old layout of land-based slot games, so Funsize Fireworks is not their first venture into this theme. However, it embraces this classic layout with an alternative outlook to provide a fresh approach to an already saturated market.

Despite the cabinet-style design of Funsize Fireworks, the reels are adorned with symbols unconventional to this traditional layout; gems, diamonds, stacks of cash and more - with the ability to trigger the elusive Fireworks Feature, for the chance to score some potentially blazing winning potential.

How to Play Funsize Fireworks


Before you play Funsize Fireworks, a stake must be set. To do this, simply use the Bet settings to select a wager value you feel is suitable for your bankroll. This can be changed after each round if you change your mind.


Once you’ve set your stake and you’re ready to play Funsize Fireworks, hit the Spin button. This will trigger the game to play through a single round at the set value, randomising the reels and highlighting any wins at the end of the spin.


21.co.uk players have the ability to play through a predetermined number of rounds automatically. Use the Autoplay settings to select the number of spins you’d like to play, setting a single win limit in the process - the feature will end prematurely if this limit is hit, or if the Fireworks Feature is triggered.

Funsize Fireworks Special Features
