How to Play

Here are a few steps to play this game:

  1. Load Flex Game on your smartphone or desktop
  2. Use the “–” and “+” buttons to vary your coin value and the total bet
  3. Click any card to deactivate it
  4. Press the play or flash button to begin

Flex Game has 15 winning lines with 4 cards. Although you get 30 balls, there is a bonus for extra balls. There is also an option to buy up to 14 extra balls and a progressive jackpot.

The minimum bet in Flex Game is €0.04, while the maximum is €80.

Flex Game RTP and Volatility

Flex Game uses a low volatility engine and has a variable RTP with a default of 97.5%.

The Return to Player (RTP) rate of 97.5% is pretty high and way above the industry standard. While that is intriguing, it is variable, and some online casinos may offer less than that amount. Notwithstanding, having a high RTP with low volatility is a recipe for exciting gameplay.

There is no high risk in Flex Game, making hitting wins easy. You can expect regular low-paying wins in a gaming session, but the high-paying wins might be elusive for a while.

High rollers do not often like low volatility games because of their payout potential. However, such titles are the perfect start for new players, offering lower risk and more frequent wins. Payouts in Flex Game will be substantial, as the high RTP means you keep a significant part of your wins.


Flex Game

Play’n GO’s design language for Flex Game has a clutter-free look. Although the game has 4 cards, it makes good use of the screen's size with a good amount of visibility. Playing it is visually appealing and straightforward, as you can see the winning patterns above the cards.

The controls, cards, patterns, and other crucial features contrast nicely with the plain blue background. There is a sound effect during the ball drops and winning patterns, but no soundtrack. While that makes the gameplay less immersive, the simplicity enhances the thrill, excitement, and focus on the play area.

Flex Game uses an array of balls ranging from 1 to 99. Notwithstanding, every spin releases 30 balls onto the grid.

The 4 playing cards carry random values from 1 to 99, in line with the value of the balls. Being a Bingo means you do not get a payout from each ball value. Instead, the cards that contain the number of balls in the winning pattern win.

You can click the New Cards button to change the numbers on each card. However, the total number of winning patterns for a card remains 15.

Mobile Compatibility

Flex game slot mobile
Flex Game runs fluidly on mobile devices, whether on Android or iOS. Play’n GO’s heavy use of HTML5 framework shines with this game, as gameplay is smooth and appealing.

The controls move from the right side of the screen to the bottom on mobile devices. Notwithstanding, they are bold and wide enough for easy operation.

The balls are a little too tiny for the fingers, but they are still functional. You must be careful when picking them during the bonus features.

About Play’n GO

Play’n GO’s giant strides in the casino games industry are indisputable. The game provider has consistently rolled out high-quality games since its independence in 2005. Before then, it operated as a subsidiary of industry-leading companies.

This company is good at what it does, and its games attest to that. It has over 300 games, with more than half held by slot machines.

This software provider’s efforts have accorded it several recognitions, including the Best Casino Supplier of the Year. It won the prestigious award at the 2019 Malta iGaming Excellence Awards. Other Play’n GO games you can try include Rise of Olympus, Legacy of Egypt, Sisters of the Sun, and Scroll of Dead.

Bonus Rounds & Free Spins


Flex Game has a few bonus features that add color to the gameplay. They might seem basic, but their appearance brings the big wins in the game.

Extra Balls

The first bonus you will most likely trigger is the extra ball feature. After the initial 30 balls have landed, the game might randomly bring a new array of balls. It can allow you to pick a specific number of free balls and add to the initial 30.

That brings one more opportunity to win or complete a winning pattern.

Tap Bonus Round

Activating this bonus feature requires winning with a perimeter pattern. A new screen will pop in with several icons. All you have to do is pick 6 icons to win the prizes lying underneath.

Progressive Jackpot

This bonus holds the highest win in Flex Game. Also, winning is straightforward and happens instantly, although still random.

There are about three requirements to unlock the jackpot feature. First, land a bingo on any 4 cards, but they must be active during the play.

Flex Game Demo Play

You don't have to search further if you want to quickly get your hands on the free version. The demo play of Flex Game is available on this page, and you can play without any deposit. Scroll down and click it to load the demo.

Max Win

Flex Game has a max win of 7,200x your stake.

Although this game has 3 bonus features, players can only win the maximum payout if they trigger the progressive jackpot. Notwithstanding, it does not end with activating the bonus feature.

The highest payout is 7,200x the stake, but you must place the maximum bet to hit the biggest or jackpot prize. Also, the jackpot is progressive, meaning the prize will likely increase as more players join.

Then again, you will wrestle with low volatility to hit the jackpot. The variance will quickly push out low-paying wins, but hitting high-paying wins will not come easy.

Overall Rating


Flex Game has exciting gameplay that is a refreshing deviation from the typical casino games. It has a decent maximum payout, and the low volatility engine will produce frequent but low-paying wins.

Grabbing the maximum win in Flex Game is straightforward and requires just one bonus feature. Hitting the jackpot at the maximum bet will give you the biggest payout. Nevertheless, you will enjoy the game if you are patient and content with the low-paying wins from the mild volatility.
