Frequently Asked Questions

How long does it take to build a slot game?
Depending on complexity, a full-cycle slot project usually takes 10–20 weeks, including math design, art, coding, and certification.
What is RTP and volatility?
RTP (Return to Player) defines payout percentage over time, while volatility controls risk/reward balance - we adjust both based on audience behavior.
Which technologies do you use?
We mostly use Unity, HTML5/TypeScript, C#, and custom RNG frameworks. All the games work on different platforms. Each game is made to run well on mobile too.
Can you help with certification or integration?
Yes, we help with GLI, BMM, and MGA rules. We also work to connect games with big casino systems like SoftSwiss, EveryMatrix, and Slotegrator.
What makes your slot games perform better?
A good balance in the math, a clear game look, and a setup made for what players want. These things get better with real numbers and LiveOps help.
