Angry Balls: the slot that swapped reels for an Angry Birds slingshot
If you ever flicked a bird at a pig tower on a phone, you already know how to play this. Angry Balls keeps the slingshot and the collapsing wood, swaps the birds for spiked balls, and pays out on what you smash: 96.51% back on average, a ceiling of 37,168x, and a stake that starts at 0.10. One shot per round. No reels, no paylines, no waiting for a bonus to trigger.
Angry Birds on a casino floor: what changed, what stayed
The slingshot stayed. So did the wooden planks, the stone blocks, the satisfying crunch when a tower gives way. Coreffect Interactive built the game around the one thing everyone remembers from Angry Birds, and Stake sells it under the tag Only on Stake. What changed is the target: instead of pigs you are hitting coins, and every coin the ball touches adds to one multiplier. A bronze coin adds +0.25x, a diamond +10.00x. When the ball finally stops, the multiplier meets your stake and that is your round.
Two things to know before you get comfortable. First, there is no licence from Rovio anywhere in sight: Stake calls the game inspired by the Angry Birds franchise, and that is the whole extent of the relationship. Second, the tower is hidden until the ball is already flying, so the angle you pick is a bet on geometry you have not seen. I spent my first evening switching angles after every miss. Do not do that. The round, move by move, is on the how to play page.
Four screens from the game itself
Taken in demo mode, not drawn. If you played the phone game, the first one will look like home.
-
The whole game fits one screen: slingshot in the middle, multiplier above, balance and bet below. -
Pull the ball back until the circle turns green, then let go. Half pulls do not fire. -
The game states the same values this site does: +0.25x to +10.00x, plus Split, Grow and Ghost. -
The wheel sectors run to 1,000x. It only appears after a full clear, and it is the screen you want to see.
Screens captured in free play at Stake, so the balance shown is play credits.
Pick angle 1 and stop thinking about it
Six angles, six pairs of numbers. Angle 1 keeps the highest return and the highest ceiling at the same time, so the rest of the dial is a trade, not a choice. I still test the others in demo now and then. They still lose.
| Angle | RTP | Max win |
|---|---|---|
| 1 | 96.51% | 6,500x |
| 2 | 96.51% | 4,500x |
| 3 | 96.50% | 3,625x |
| 4 | 96.49% | 3,725x |
| 5 | 96.48% | 3,650x |
| 6 | 96.49% | 3,225x |
Angle figures come from the SlotCatalog review of the game. Return moves by three hundredths of a percent across the dial; the ceiling drops by more than half. The full breakdown is on the RTP page.
Three power ups float in the gap the ball crosses
Catch one and the shot changes in flight. Catch two and they stack. This is the part the phone game never had.
-
Split
Adds balls to the shot, so three fly at the structure instead of one.
-
Ghost
The ball passes through walls and still breaks a coin on contact.
-
Grow
Raises the size and the mass of the ball, which helps it punch through.
No free spins. Two paid shots instead
You can pay a multiple of your stake to change the physics or the tower. One mode throws a bomb, the other fills the layout with treasure.
| Mode | Cost | Max win | What changes |
|---|---|---|---|
| Bomb Mode | 25x | 7,951x | The ball becomes a bomb that detonates on contact with the structure. |
| Max Treasure Mode | 100x | 37,168x | Every layout is filled with the highest number of coins and diamonds it can hold. |
Max Treasure is the only route to the 37,168x headline, and it costs 100 times your stake per shot. Cost against ceiling is compared on the bonus buy page.
The counters say people found this game
Stake publishes running totals on the game page, and they are not small. Over the 28 days before 26 August 2026 the game took $3,405,111 across 1,182,731 bets and returned 96.14%. Over 24 hours the same counter read 87.28%, which is what a short sample looks like on a game whose ceiling is this high.
On Stake Engine, the platform under the game, it stood at number 57 by 30 day turnover among 3,368 live titles, with $8,146,367 from 2,943,179 bets. For a studio with three games to its name, that is a crowd. The platform numbers are laid out on the Stake page.
What people ask before the first shot
Is Angry Balls an official Angry Birds game?
No. Stake describes it as inspired by the Angry Birds franchise, and neither Stake nor Coreffect Interactive claims a licence from Rovio. The slingshot and the physics are borrowed; the birds became spiked balls. What carried over and what did not, side by side.
Where can I play it?
At Stake and nowhere else. The game carries the Only on Stake tag and runs on Stake Engine, so catalogue sites cannot host the demo either.
What is the real maximum win?
Depends on the mode. At the base rate the ceiling is 6,500x at angle 1 and falls to 3,225x at angle 6. The 37,168x figure belongs to Max Treasure mode, which costs 100x per shot.
Can I try it without money?
Yes, and you should. Demo mode runs on the game page itself with play credits. What the demo shows and what it hides.
