Atomic Slot Lab is turning up the voltage with "Amped Up!", a reimagined 3x3 stepper slot that hits casinos on 24 July 2025. Designed to bridge nostalgic appeal with contemporary slot mechanics, this new release delivers a streamlined yet dynamic experience for modern players.
Amped Up! follows in the footsteps of traditional stepper slots but adds a modern punch. With 5 or 9 selectable paylines, players can choose their level of risk and reward. Classic slot symbols like multi-coloured sevens and bars come charged with multipliers of up to 10x, and top-paying wilds offer the chance to build paylines with greater flexibility.
Random respins on any win add an unexpected twist. These respins progressively increase the payout, keeping adrenaline high for players chasing that next big win. With medium volatility and an RTP (return to player) of 94.00%, the game is tailored for those who want a balanced mix of excitement and consistency.
"The line selector gives players extra flexibility, while multicoloured sevens and bars can boost their wins with handy multipliers of up to 10x," said Atomic Slot Lab.
"Top-paying wilds may help them create winning paylines as they teeter on the edge of their seats, expecting lucky random respins with increasing payouts on any winning spin."
Amped Up! kicks off a string of summer slot releases from Atomic Slot Lab. Following its launch, players can look forward to:
Book of Thieves - 31 July
Happy Lucky - 5 August
Fortune Filer - 12 August
Each release continues the developer's trend of pairing recognisable slot mechanics with fresh design and creative features, aimed at keeping both seasoned players and newcomers engaged.
Amped Up! marks another entry in the industry’s effort to merge classic gameplay with newer digital innovations. For players who love the simplicity of stepper slots but crave modern incentives like respins and multipliers, this game offers an ideal middle ground. The flexible paylines and accessible format make it easy to pick up, but hard to put down.

Most of my career was spent in teaching including at one of the UK’s top private schools. I left London in 2000 and set up home in Wales raising four beautiful children. I enrolled at University where I studied Photography and film and gained a Degree and subsequently a Masters Degree. In 2014 I helped launch a new local newspaper and managed to get front and back page as well as 6 filler pages on a weekly basis. I saw that journalism was changing and was a pioneer of hyperlocal news in Wales. In 2017 I started one of the first 24/7 free independent news sites for Wales. Having taken that to a successful business model I was keen for a new challenge. Joining the company is exciting for me especially as it is a new role in Europe. I am keen to establish myself and help others to do the same.
