History of Mega Block Slot

The Origins of InOut Games
InOut Games is a casino software provider founded in 2024 in Malta, with operational offices in several European capitals. The company was born from the vision of a group of veteran iGaming industry developers, determined to create innovative gaming experiences that would stand out from the mass of traditional slots.
The founding team boasted previous experience at industry giants such as NetEnt, Microgaming, and Play’n GO. This combined experience allowed InOut Games to launch high-quality products from the very beginning, quickly earning the trust of online casino operators.
The Birth of Mega Block
Mega Block slot was officially released in November 2025, after over 18 months of development. The original concept was born from observing the success of puzzle games like Tetris and Candy Crush, which had demonstrated how “match and clear” mechanics could create positive engagement in players.
The InOut Games development team decided to merge these mechanics with the excitement of gambling, creating a unique hybrid of its kind. The result was Mega Block, a slot that maintains the adrenaline of random wins while introducing strategic elements absent in traditional slots.
Evolution and Updates
Since its initial launch, InOut Games has released several updates for Mega Block slot:
- December 2025: Added Turbo Spin mode
- January 2026: Introduction of 4-level Progressive Jackpot
- February 2026: Mobile device optimization and new sound effects
Each update has improved the gaming experience while keeping the 96.5% RTP intact, thus ensuring fairness and transparency for all players.

The 96.5% RTP System
The RTP (Return to Player) of 96.5% means that, statistically, for every €100 wagered, the game returns €96.50 to players over the long term. This value is significantly higher than the industry average (around 95.5%) and positions Mega Block by InOut Games among the most generous slots available.
It’s important to understand that RTP is calculated over millions of spins, so individual sessions can vary considerably. However, a higher RTP increases the theoretical probability of winning over time.
7x7 Grid Architecture
Unlike traditional slots with 5 reels and 3 rows, Mega Block slot uses a 7x7 block grid, for a total of 49 play positions. This larger structure offers more possibilities for winning combinations and makes each spin visually more dynamic.
Provably Fair Technology
InOut Games implements Provably Fair technology in Mega Block, which allows players to verify the fairness of every single spin. Through a cryptographic hash system, it’s possible to confirm that results have not been manipulated by either the operator or the provider.
Main Features of Mega Block

🎮 Innovative Block-Based Mechanics
Unlike traditional slots with spinning reels, Mega Block uses a falling block system similar to puzzle games. When winning combinations form:
- Winning blocks disappear from the grid
- New blocks fall from above to fill empty spaces
- Multiple chain reactions can occur
- Each reaction increases the win multiplier
This mechanic creates a dynamic gaming experience where a single spin can generate multiple consecutive wins. Experienced players know that the best sessions on Mega Block slot occur precisely when long chains of reactions are triggered.
💰 Progressive Multiplier System
The multiplier system is one of the strengths that make Mega Block by InOut Games so popular:
| Chain Reactions | Multiplier | Example (€1 Bet) |
|---|---|---|
| 1 reaction | 1x | Base win |
| 2 reactions | 2x | Win doubled |
| 3 reactions | 3x | Win tripled |
| 4 reactions | 5x | Win x5 |
| 5+ reactions | Up to 10x | Maximum win |
Multipliers apply to wins obtained in that specific reaction, allowing players to reach the maximum win of 5000x the stake during particularly lucky sessions.
