FluxPlays verdict
Our verdict
No, unless you buy through X-iter. A Bomper turns wild once enough symbols have hit it, and in the free drops and X-iter runs its meter and wild state carry from drop to drop, so the wilds build up. The drawback is the paytable: even several sticky wilds mostly pay fruit amounts, and in the base game the Bompers seldom appear at all.
Who it suits
Play this if…
- Bonus buyers: every X-iter option keeps the base game's RTP, from three paid drops up to the bonus
- Learners: the Bomper meters show exactly how close each one is to turning wild
- Players who like a bonus that builds: Bomper states carry from drop to drop in the free drops
Skip this if…
- Short-session players: Bompers appear before few base drops, and fruit wins between them are tiny
- Max-win hunters: the lines through sticky wilds rarely pay more than fruit amounts
- Anyone who wants the bonus to come naturally: it needs three bonus symbols at once, and the menu is the realistic route

Bompers: Full Review
In Bompers, the pinball bumpers on the grid are the whole game: every symbol that drops onto one fills its meter, and a full Bomper turns into a sticky wild. ELK Studios released it in March 2021 as the first game with X-iter, its menu of paid modes, on a 6x4 avalanche grid that can grow to eight rows. It suits players who like to buy short runs of a feature more than wait for a bonus.

How Bompers works
Wins pay on ways: matching symbols on adjacent columns from the left, three to six of a kind. Winning symbols drop out, new ones fall in, and every avalanche in a cycle adds a row to the grid, so the ways grow with each one:
| Rows | 4 | 5 | 6 | 7 | 8 |
|---|---|---|---|---|---|
| Ways | 4,096 | 15,625 | 46,656 | 117,649 | 262,144 |
The paytable is small for that many ways, with six 7s at the top paying $10.00 on a $1 bet:
| Symbol | Six, at $1 | Five | Four | Three |
|---|---|---|---|---|
| 7 | $10.00 | $3.00 | $2.00 | $1.00 |
| BAR | $3.00 | $2.00 | $1.00 | $0.50 |
| Horseshoe | $2.00 | $1.00 | $0.60 | $0.30 |
| Clover | $1.00 | $0.60 | $0.40 | $0.20 |
| Watermelon, orange | $0.60 | $0.40 | $0.20 | $0.10 |
| Lemon, cherry | $0.30 | $0.15 | $0.10 | $0.05 |
A wild stands in for every pay symbol, and a line made only of wilds pays as the 7. Everything bigger than that comes from what the special symbols do to the grid.
Bompers, Mystery Bombs and Shooting Stars: what changes the grid
Up to five Bompers can appear before a drop, and they are the reason to play:
| Symbol | What it does |
|---|---|
| Bomper | Sticks to its spot and counts every symbol that hits it in a meter; when the meter is full it becomes a sticky wild |
| Mystery Bomb | At the end of the avalanche cycle turns itself and every connected symbol into one random symbol; where two bombs overlap the symbols turn wild; next to a Bomper it adds one meter level |
| Shooting Star | Moves up into empty space and, at the top, creates a group of up to seven symbols, up to three of them wild, that falls back down |
So the order of events matters. A Bomper only pays once it has filled up and turned wild, and a full meter needs symbols to keep landing on it, which is what long avalanche cycles provide. Outside X-iter and the bonus, nothing guarantees that a Bomper appears before a drop at all.
The Bompers bonus: how the free drops trigger
Three bonus symbols anywhere start 7 free drops. Each one begins at four rows, and up to five Bompers appear at the start. What changes is memory: a Bomper's meter and its wild state carry over from one free drop to the next, so a Bomper filled on drop 2 is still a sticky wild on drop 7. Three more bonus symbols retrigger the free drops, and the bonus pays its total at the end.

X-iter: prices and what you get
X-iter is ELK's buy menu, open in the base game only. One option buys the bonus outright. The other three buy a set number of drops with Bompers guaranteed, one more Bomper on each drop, and the Bomper states kept from drop to drop:
| Option | Type | Price at $1 | Official RTP and volatility | What you get | Our test |
|---|---|---|---|---|---|
| X-iter 1 | Paid drops | $25 | 95.8%, 8 of 10 | 3 drops with 1 to 3 Bompers | One run: $30.70 back |
| X-iter 2 | Paid drops | $50 | 95.8%, 8 of 10 | 5 drops with 1 to 5 Bompers | One run: $8.25 back |
| X-iter 3 | Bonus buy | $100 | 95.8%, 8 of 10 | The bonus: 7 free drops | One round: $100.85 back |
| X-iter 4 | Paid drops | $300 | 95.8%, 8 of 10 | 10 drops with 1 to 10 Bompers | One run: $65.60 back |
Every option carries the base game's RTP, so the menu is a choice about pace, not about value. The multi-drop options are not a bonus: they are ordinary drops with Bompers forced onto the grid, and the cheapest is the shortest look at the meters filling.

RTP, volatility and max win
The 95.8% in the rules is the version we played, and the casino decides which one it runs. ELK's data sheet puts its volatility at 8 on a scale of 10, listed as High in the table above. It also gives a hit frequency of 19.9%, and every win stops at 5,000x the bet.

Tested on ELK Studios' official USD demo on 1 November 2026 (rules last updated 17 January 2022, X-iter rules 8 October 2024), from a $5,000 demo balance, at the default $1 bet. The 100 base drops came first, then each X-iter option once at the $1 bet level. X-iter 1, 2 and 4 are single purchases of a fixed number of drops and are listed under paid modes. The window rendered slowly, so the game's animation timer was driven by a script; game logic and server calls were untouched. Session: $575.00 staked, $260.85 back, ending at $4,685.85, matching the server and the screen.
Bompers came alive only when we paid for them. In the base game they turned up before just two of our drops, and the bonus never arrived, so most of the session was a fruit avalanche with small wins. The best was spin 58, the one round whose avalanche climbed all the way to eight rows.
The X-iter runs showed the meters doing their job and the paytable limiting them. The bought bonus had four sticky wild Bompers by free drop 4 and still finished at about its price, because fruit lines through wilds pay little. The ten-drop run filled several Bompers too and came back at under a quarter of its cost.
Our bought bonus ended at $100.85. FluxPlays demo test, 1 November 2026.
A retrigger, and the Mystery Bomb and Shooting Star as separate events, did not show in our log, so they come from the rules. One session of a game rated 8 out of 10 shows how the Bompers work, not what the menu returns.
Our ten-drop X-iter run ended at $65.60. FluxPlays demo test, 1 November 2026.
Is Bompers worth playing?
The reason to play Bompers is X-iter. The Bompers are a good idea, a wild that has to be earned by filling a meter and that stays once it is, but the base game rarely gives them the long avalanche cycles they need. X-iter fixes that at the same RTP, and the bonus adds memory between drops.
The limit is the paytable. Even a grid with several sticky wilds pays fruit amounts unless the 7s or bars line up, and our paid runs showed it more than once.
Pick Cygnus, ELK's earlier six-column avalanche game, if you want the same growing grid with multipliers that double instead of meters that fill. Choose Bompers for sticky wilds you can watch being built, and a menu that sells them three drops at a time.
In the demo, start with X-iter 1. It is the cheapest option, and three drops are enough to see a Bomper meter fill and turn wild.
Frequently Asked Questions
How do the Bompers work in Bompers?+
A Bomper sticks to its spot and counts every symbol that hits it. When its meter is full it turns into a sticky wild. Up to five can appear before a drop, and a Mystery Bomb next to one adds a meter level. In the free drops and X-iter runs, each Bomper keeps its state from drop to drop.
What is X-iter in Bompers, and what does it cost?+
X-iter is the buy menu, open only in the base game. X-iter 1, 2 and 4 cost 25x, 50x and 300x the bet for 3, 5 or 10 drops with Bompers guaranteed, and X-iter 3 buys the bonus for 100x. Every option has the base RTP of 95.8%.
How do you trigger the bonus in Bompers?+
Land three bonus symbols anywhere for 7 free drops. Each drop starts at four rows with up to five Bompers, their meters carry over between drops, and three more bonus symbols retrigger. It did not come naturally in our hundred base drops, so we bought it through X-iter.
What is the max win in Bompers, and how is it reached?+
The max win is 5,000x the bet. By the paytable it takes the top symbols on a grown grid: six 7s pay 10x the bet, and a full eight-row grid has 262,144 ways, so it needs 7s and sticky wild Bompers lined up across many of them.
