Coreffect Interactive: a Steam strategy studio that walked into casino
Coreffect Interactive is an independent studio founded in 2020 in Montreal, Quebec, and it spent its first years selling strategy games on Steam, not slots. That is the best thing about Angry Balls: it was built by people who model physics for a living and picked the Angry Birds slingshot because it is the most legible physics toy on earth. Three titles at Stake so far, all of them without reels.
A strategy developer that walked into casino
The studio site describes its own work in two halves. One is premium strategy and simulation released on Steam. The other is physics based iGaming built for the operator. The pitch across both is the same phrase: games driven by complex systems, simulation and procedural mechanics. Read that twice and Angry Balls stops looking like a novelty and starts looking like the obvious thing for this team to make.
That background shows up in the product. A reel game asks a random generator for symbols and pays a table. This one asks a random generator for a tower and then simulates what a ball does to it. The result is the same in probability terms and completely different to watch, which is most of why clips of the game get shared as the Angry Birds casino game.
What the studio has released so far
Two Steam titles and three games at Stake. The Steam side is where the studio spent its first five years.
| Title | Platform | Released |
|---|---|---|
| Roman Triumph: Survival City Builder | Steam | 16 September 2025 |
| Chess with Lasers | Steam | 14 September 2021 |
| Golden Goal | Stake | listed on the studio page |
| Angry Balls | Stake | 2 January 2026 |

Roman Triumph is a paid city builder, not a free to play product. Contact for the studio is contact@coreffect.ca, published on its own site.
Three habits that carry across its games
Look at the three wagering titles together and the same design habits appear in all of them.
-
Physics decides the picture
Outcome and animation are the same event. A collapsing tower is not a payout animation played after the fact.
-
One decision per round
You choose an angle, or you do not play. There is no bet slip full of side options, and no free spin queue to sit through.
-
Systems over symbols
No paytable of fruit. Coins carry values from +0.25x to +10.00x and everything else comes from what the ball does to the tower.
How a three game studio ended up in the top hundred
On 26 August 2026 the game ranked 57 by 30 day turnover on a platform carrying 3,368 live titles from 955 publishers. Above it in that table sit studios with dozens of releases each. This one has three.
The ranking is turnover, not quality, and turnover follows attention. A physics game that looks like a game people already know travels further than its catalogue position would suggest. The platform figures are on the Stake page.
