Introduction
Why enjoy a birthday party once a year when you can have one every day of the week with this colourful slot from Eyecon? The champagne is flowing and there are balloons aplenty as reels filled with party blowers, hats, gifts, cupcakes, and flowers hopefully spin in the wins. If this is not a big enough treat, there are scatters, wilds, free spins, and a gamble bonus to really get you in the party mood.
Happy Birthday Theme and Storyline
This is a party themed slot with reels filled with birthday gifts and party favours. There are balloons floating above and below the reels and chasing lights around the reels to try to add to the celebratory feel.

Happy Birthday RTP and Variance
The theoretical return to player ratio of this low variance game is 95.436 per cent. This is not far off the industry average but may still seem a little low if you are used to playing games with an RTP nearer or above 96 per cent.
How to Play Happy Birthday
Start the party early with the following top tips for playing the Happy Birthday slot:
- Start by deciding if you want to spin with sounds or not. If you choose to press the tick button then you’ll be treated to mechanical spinning sounds and electronic tones when wins roll into place. You may even get a rendition of the Happy Birthday song if you’re lucky.
- Click on the stack of chips to choose your bet. You get to choose how many of the 25 paylines you want to play and how much you want to bet per line. This will create your total bet per spin.
- If you want to jump straight to the maximum number of paylines and the top bet possible, there are Max Line and Max Bet buttons to press. Just remember that betting the maximums will make your playing balance go down much quicker than they might otherwise do. This is great if this is how you like to play, but just make sure that you always bet responsibly and never stake more than you can really afford.
- Use the question mark button to access the game information. This is where you will find out details about the special features offered in the game.
Happy Birthday Bet Sizes & Paytable Wins
You can start playing this game with just 1 winline at a bet of 0.01 per spin. At the other end of the scale, you could play all 25 winlines at a maximum bet of 0.50 per line. This creates a top bet of 12.50 per spin.
There are wins available for matching at least two symbols, although this only applies to the higher paying icons in the game. The lower value symbols need you to land at least 3 matching icons to reward you with a prize. The biggest prizes are obviously reserved for maximum bets and 5-of-a-kind combinations and include:
5x streamers 9,500
Purple hippo and panda 950
Champagne bottle 450
Champagne flutes 250
There are also balloons, cupcakes, flowers, musical notes, gifts, party hats, and party blowers offering prizes of between 250 and 100 for 5-strong combinations of matching symbols.
There is a gamble bonus after wins that allows you to risk your prize in the hope of doubling your win. This is a typical pick ‘em game and will result in you losing your win if you make the wrong choice.
Happy Birthday Bonus Features
As you might expect from a good birthday party, this slot has a few nice surprises up its sleeve. These include:
Free games
Land at least 3 of the cake scatter symbols and receive 15 bonus spins. Any wins that land during these free spins will be tripled. You can also retrigger the bonus up to a massive 15 times.
Wild symbols
The streamers are the wilds of the slot and can replace any other symbol except for the cake scatter to help you to create winning combinations of symbols. If a wild is involved in a win your prize will be doubled.
Scatters
As well as triggering the free games bonus, the scatter symbols can also deliver wins all of their own. They are based on a multiplier of your total wager, rather than just your bet per line and there are wins available for matching between 2 and 5 of the cake icons.
Happy Birthday Review
This choice of Eyecon slots has a great array of bonus features and some added extras to enhance the party spirit. The most popular bonuses are there, such as free spins and wilds and the appeal of these are boosted further by the addition of double and triple wild multipliers. The graphics are clean and the overall design is colourful and fun. It’s just a shame that it doesn’t feel particularly party-like, despite some obvious effort by the makers. There is something a little lacking in the va-va-voom area, making it feel like a party held by an elderly family member rather than a wild night out on the town. If you still like the efforts of this maker, however, you may want to check out Eyecon's Pig's Feast slot.
