What is Tiger Stacks?
The Wednesday announcement promised the merger of the two listed gaming giants would create the second-largest listed global gaming and sports betting operator, with a pro forma adjusted EBITDA of approximately €2 billion ($2.3 billion).
Angelozzi, who is set to lead the combined company as CEO, told analysts on the post-announcement call that the deal was expected to be a “low-risk proposition” given the consistent growth demonstrated by both Lottomatica and Cirsa in recent years.
Between H1 2024 to H1 2026, Lottomatica and Cirsa have grown their revenues at CAGRs of 13% and 11% respectively.
How to play Tiger Stacks
In practice, the colored fireballs feed matching pots that shape how the Power Spins bonus plays out. Trigger the bonus game via the green fireball and the feature runs with the Expand enhancement; any green scatters that land can unlock up to three additional rows. The Collect and Multiplier variants offer alternative routes into the same bonus framework.
The significance here isn’t the individual modifiers. It’s the reuse pattern. Blueprint is carrying a differentiator across the franchise, reinforcing a recognizable identity rather than asking returning players to learn a new core engine.
The pattern reflects a wider supplier tactic: building recurring mechanical families so a proven feature can be redeployed across multiple titles. That approach lowers development risk and reduces the familiarity barrier for players. For operators, it typically means a steady supply of new content that behaves in predictable, sellable ways.
