Dream Tech is the company behind the making of the Happiness Overflow slot machine. It is an online video slot that allows game enthusiasts to try something innovative. The graphics of this slot machine tell it all. It is all about happiness, and that is what the players are striving to achieve even with the expected wins. The slot machine uses a 9x9 grid layout. You can play this video slot on both desktop and mobile devices. It features a theme of Fireworks that fill the reels as players collect their winnings. 

What Happiness Overflow RTP is 

Happiness Overflow RTP is 97.07%. This is an impressive return to player rate compared to what most online slots give. This means that you stand a high chance of winning in this game. For every 100 coins that you bet, you are likely to get 97 of them back. 

How to play 

The gameplay of the Happiness Overflow casino slot is simple. During the game, special fireworks display and ships move behind the reels. Every reel has fireworks on top of it. If you spin and manage to ignite the fireworks, you will get your prize multiplied by a predetermined figure. 

So, the game is all about helping your character create a fuse that will ignite the fireworks on top of the reels. Unlike other games, there are no classic or special symbols here. 

To start the game, you will have to load it on your device. This happens automatically when you open the game. The next step is to select the bet size before you spin the reels. There is no minimum betting amount; you can bet from as low as 0.01 to a maximum of 250 coins. When you are done, you should click on the spin button. There is an auto-play option. 

Responsible betting dictates that you only bet an amount that you are comfortable with. Don’t go out of your budget to place a bet.

How to win

With an RTP of 97%, players are excited about the prospects of winning in this game. It doesn’t disappoint. Playing the Happiness Overflow slot game has real chances of winning real money. But you have to play for real money to be able to withdraw. 

Since there are no regular and special symbols in this game, winning combinations might be somewhat different from regular online slots. When you play Happiness Overflow slot, your target is to ignite the fuse to burn a winning combination. Every combo has a number attached to them. The winning that you get depends on the combo burned. 

Higher combos reward more winnings. For example, if you burn Combo 9, you will get 1000x your bet. When reloading the game, you can also launch the fireworks level, which pays more. 

Symbols and soundtrack

It’s all about fireworks in this game. You must recognize that there are no regular symbols used in this game as it is with other online slots. But this doesn’t mean that you play in isolation. The reels are full of fuses that lead to various destinations that reward prizes. The sound is reflective of the mood of the game.

Since there are no symbols here, the paytable shows combinations of what a fuse can burn. The fuse is interconnected and can burn multiple fireworks. The combo number determines how much you win. 

  • Combo 1 x 25 
  • Combo 2 x 25
  • Combo 3 x 50
  • Combo 4 x 80
  • Combo 5 x 120

  • Combo 8 x 500
  • Combo 9 x 1000

There are not many Happiness Overflow bonuses. This is one of the drawbacks of this slot machine. It only presents one bonus feature to players.

There is no special reward in level one. Rewards begin from level 2 up to level 10. In between, you will get rewards ranging from 10x to 1000x depending on the level launched when playing Happiness Overflow online. The highest level rewards the highest payout.
