5 Men Gaming has mixed iconic classic symbols with the Batman films to create So Serious Joker, a no-frills, back-to-basics slot. The joker and the star are the wild and scatter symbols respectively, with both paying out on up to 40 paylines. The only extra feature in So Serious Joker is the optional risk game that can be played after any winning spin.

Theme, graphics & soundtrack

One of a range of film-inspired slots available here at Slots Temple, So Serious Joker from 5 Men Gaming takes its inspiration from various incarnations of the Joker from the Batman universe. A chilling image similar to Heath Ledger's Joker appears in the backdrop above a dark city skyline, while the maniacal laugh that accompanies the wins in the risk game is not unlike Joaquin Phoenix's portrayal in the movie Joker. On the reels, however, the Joker symbol is cartoonish. It takes on the role of the wild in this slot, while the scatter symbol is a shiny gold star. Brightly-coloured fruit and two variations of the traditional 7 symbols make up the remainder of the icons on the reels.

As with many of the 5 Men Gaming free play slots, there is no background musical soundtrack; instead, it relies on sound effects only for its wins.

How to play So Serious Joker

1. Once the slot has loaded, select the information icon to check out the paytable and rules of the game. The arrow to the right of the information button enables you to page between the paytable information and rules.

2. The full-screen and sound settings can be found to the top right of the screen.

3. Adjust your bet size by using the + and - buttons on either side of the lines, bet/line and credit windows.

4. If you want to use autoplay, toggle it on. The reels will spin automatically for an unlimited number of spins until the toggle is switched off. There are no loss or balance limit settings for autoplay.

5. When the symbols land in a winning combination, the gamble button will light up and give you the option to play the risk game. The risk game is unavailable during autoplay or if the winning amount is over 500x the number of active paylines.

6. Press the start button for your first spin.

Remember to play responsibly, taking frequent timeouts to ensure you stay in control. We recommend that you play the free demo version here at Slots Temple before deciding whether to play for real at an online casino; in this way, you will get a feel for the gameplay and the potential returns.

So Serious Joker bonus feature

- Risk game

Due to its more classic design, So Serious Joker doesn't have the scatter-triggered bonus feature found in most modern online slots; however, it does have an optional risk game. After a winning spin, you will have the option to either gamble or collect your winnings. Opting to gamble will take you to the risk game, which gives you the option to bet the winnings of the spin on the turn of a playing card. If you predict the colour of the card correctly, you will double your winnings, while an incorrect prediction loses all the winnings for the round. You can keep doubling until you reach the maximum bet of 500x the number of paylines selected in your current bet; for example, if you are playing 40 lines on the base game, the maximum bet on the risk game will be 20,000.

Our verdict

While So Serious Joker looks great, its low variance, low hit rate and lack of bonus features may feel repetitive to players who are used to a more complex experience. The scatter symbol has no purpose other than providing another payout combination and the sound effects can become irritating, although these can be switched off in the settings. If you are a fan of the Joker and prefer a more classic-style slot, So Serious Joker ticks these boxes. Fans of the Batman universe looking for bonus games or progressive jackpots may prefer Playtech's Batman Vs Superman slot. Based on the movie of the same name, this has medium volatility and a slightly higher RTP.
