Overall Opinion about Happy Birthday

Happy Birthday has many things going on for it. It has simple and easy-to-understand gameplay with uncomplicated features. Special features like the Scatter symbol triggers the free games and, at the same time, also pay prizes when you land two or more on the reels. Furthermore, when you land two or more Wild symbols, the slot machine pays out some incredible prizes. The only obvious downside that many players have complained about this game is its betting range. While it is very accommodating for low-stakes players, the betting limit is too low for high rollers.

Happy Birthday Theme and Unique Features

Your birthday is supposed to come up once a year, but on the reels of Happy Birthday, the party never stops. Eyecon developed this video slot with a birthday theme, which is evident from its designs, soundtrack, and symbols. You will find birthday party props acting as paying symbols in the game. The slot machine is not lacking in terms of feature, as it has Wild and Scatters that also pay.

Happy Birthday Bonus Features

The following are the incredible bonus features that will turn your usual day into a party:

  • Wilds – The streamer symbol is the Wild, and it will substitute all other symbols except the Scatter symbol to create winning combinations. Additionally, all line wins formed with the help of Wild substitution are doubled. Interestingly, the Happy Birthday Wild symbols function doesn’t just stop with this. Landing two or more Wild symbols will earn players some incredible wins capped at 9500x players’ bet.
  • Scatter – A birthday party is not yet complete without a cake, so this game’s Scatter symbol is a birthday cake. The Scatter symbol is solely responsible for triggering the game’s Free Spins feature. In addition to this, landing two or more Scatter symbols anywhere on the reels will earn players some incredible wins. These Scatter winnings will be multiplied by the total bet per spin and not the bet per line.
  • Free Spins Feature – Landing three or more Scatter symbols anywhere on the reels will automatically trigger the Free Spins feature and automatically award 15 free games. You should note that the free games triggered at any time will use the current bet and number of active paylines of the round that triggers it for payouts. During this free games feature, all winnings earned will triple. Furthermore, you can still retrigger more free games up to 15 times during this feature.
  • Gamble Bonus Round – After every win in this video slot game, the gamble bonus option, where players will get the chance to try and double their winnings, will come up. Here, you will guess which one out of two symbols the game will reveal. A correct guess will double your winnings, while an incorrect one will see you lose it.

Happy Birthday Payouts

The total bet per spin in the Happy Birthday game is the current bet per line multiplied by the number of active lines in the game. Even with 25 paylines, the maximum bet limit in Happy Birthday is just 12.50 credits, while the minimum is 0.25 credits. However, if a player uses only one line, the minimum bet is 0.01. The low betting range makes the game very suitable for casual and low-stakes players. The maximum amount paying symbols can pay in this game is 950x players’ line bet, and at the same time landing five Wilds will pay out a whopping 9500x players bet per line.

Symbols 5x 4x 3x 2x
Hippo Toy 950 150 25 2
Panda Toy 950 150 25 2
Champagne 450 100 20 2
Champagne Flutes 250 75 10 2
Heart-shaped Balloons 250 75 10 2
Cupcake 125 25 10 N/A
Bouquet 125 25 10 N/A
Music Note 100 20 5 N/A
Gift 100 20 5 N/A
Party Hat 100 15 5 N/A
Party Blower 100 15 5 N/A
Birthday Cake (Scatter) 450 20 5 2
Streamers (Wild) 9500 2000 200 10

All values given in this paytable are fixed. You can calculate your winnings by multiplying your bet per line by the corresponding value for the winning combinations triggered. For example, let’s say you landed five Cupcake symbols when your current bet per line is 0.5 credits. Your winnings will be 125 x 0.5 credits = 62.5 credits. Scatter wins, on the other hand, are multiplied with the total bet per spin.

RTP and Volatility

Eyecon designed the Happy Birthday slot machine with a 95.436% return to player (RTP) percentage, which is low compared to high RTP slots but still decent enough.

Furthermore, we have observed that the video slot is a low variance game that gives out frequent wins in little amounts. However, the game is still capable of some impressive payouts.
