<pThe game is designed around a cartoonish prison theme, merging a lighthearted atmosphere with unsettling visuals. Set in the prison courtyard on a sunny day, the 6×4 game grid showcases the unicorn bench-pressing, possibly preparing for a riot. Above the reels, players will notice the Removal Meter, which activates during the Base Game. For those wanting to enhance their gaming experience at an added cost, the Feature Buy option is available in the right corner. All necessary controls, including Spin and Bet Size, are conveniently located below the reels. Winning combinations are formed by landing 3 or more of the same symbols on adjacent reels, starting from the leftmost reel.
The lower-paying symbols consist of soap, toilet paper, dice, lighter, phone, and cigarettes, with a payout of between 1X and 1.5X for landing 6 of the same type. The higher-paying symbols include a pig, raccoon, giraffe, rhino, and bunny, which pay between 2X and 7X for landing 6 of a kind.
The game features a Wild Symbol represented by a “W”, which can land with multiplier values of 2X or 3X. The Scatter Symbol, marked with the word “Bonus”, activates the Bonus Game when 3 or more are landed. During Free Spins, the Super Scatter can appear, which removes one lower-paying symbol when it lands, and landing 4 Super Scatters upgrades the Bonus Game. Let’s explore the features offered by this game.

What features are available in the slot of Happy Prison?
This slot game includes the Wild Symbol, Free Spins, and Feature Buy options.
The Wild Symbol substitutes for all symbols except the Scatter and Super Scatter Symbols, aiding in the formation of winning combinations.
This Wild Symbol can appear with multiplier values of 2X and 3X during the Free Spins. It is only available on reels 2, 3, 4, 5, and 6. Any wins that include the Wild Multiplier will be multiplied by its value, and if multiple Wild Multipliers contribute to the same win, their values will be multiplied before being applied.
This feature is triggered by landing 3 or more Scatter Symbols anywhere on the reels during the Base Game. Depending on the count of Scatter Symbols—3, 4, 5, or 6—you will receive 10, 12, 14, or 16 Free Spins, respectively. The feature can also be retriggered by landing an additional Scatter Symbol, granting an extra Free Spin.
During Free Spins, Wild Multipliers may appear with values of 2X and 3X. The Super Scatter can also activate during this feature, removing one lower-paying symbol type until the Free Spins conclude. Landing 4 Super Scatter Symbols at once will enhance the Bonus Game, eliminating 4 lower-paying symbols from the reels.
If players wish to enhance their gaming experience for a fee, the Feature Buy options include:
Bonus Bet = Activating the Bonus Bet costs an additional 30% of the current bet, which doubles the chances of triggering the Bonus Game. This option has a modified RTP of 96.15%.
100X = Activating the Bonus Game provides 10 or more Free Spins, with an RTP of 96.19%.
200X = This option activates the Bonus Game with 10 or more Free Spins and ensures one guaranteed Super Scatter, played with an RTP of 95.86%.
500X = This option guarantees the activation of the Bonus Game with 10 or more Free Spins and three guaranteed Super Scatters, with an RTP of 96.05%.
“In prison, every day is a battle against the walls, the routine, and yourself.” The prison theme has appeared in various slot games, including the San Quentin series by Nolimit City and Hellcatraz from Relax Gaming. However, Happy Prison offers a distinct take from TrueLab, combining cartoonish appeal with a gritty prison ambiance. While it may look like a humorous spin on a well-worn theme, it quickly reveals its darker side during the Bonus Game of a violent prison riot. This blend of dark humor may not appeal to everyone, yet we found enjoyment in the storytelling, which reflects the provocative trends seen in the slot industry.
In terms of gameplay, it may lack the ambition and innovation present in its design. The Base Game features a modest expression, with the Wild Symbol being the primary highlight. The heightened action, however, occurs during the Free Spins, where the Wild Multiplier adds excitement with values up to 3X. The inclusion of a symbol removal mechanic—where lower-paying symbols vanish with the landing of a Super Scatter Symbol—captured our interest, although the straightforward gameplay limits its appeal. We noted the familiarity of the Wild Multipliers and symbol removal mechanics, indicating a need for an additional feature to elevate the Free Spins experience.
In conclusion, we appreciated the uniquely dark and comedic prison theme that depicts fairytale animals embroiled in a riot for freedom. The gameplay, while secure, only features common attributes with reasonable winning potential. Despite the noteworthy design, the overall gameplay does not warrant a high score.
Happy Prison is a captivating yet gory release that delivers dark humor alongside familiar gameplay.
