Crypto Crown 40 — Bonus Features
Crypto Crown 40 runs four mechanics: expanding Wilds across the middle reels, two Scatters that pay without a line, a random four-tier jackpot board, and a straight 50/50 gamble. Here is each one in full.

How Each Feature Pays
Trigger conditions, published values and an honest read on which of these actually moves your balance. Spoiler: it is mostly the third one.
Expanding Wilds
How to Trigger
A Wild landing on reel 2, 3 or 4. The outer two reels never carry one.
What Happens
When a Wild lands on one of the three middle reels it expands to cover that column completely — four positions on this 5×4 grid. It substitutes for every symbol except the Star and Diamond Scatters, so any payline running through that column can be completed by it. With three eligible reels, a single spin can end up with the entire middle of the grid turned Wild.
Values
None attached. The Wild adds coverage, and the payout is whatever the completed lines are worth.
Variants
The four-row grid is what separates this from the 10-line version — an expanded column here is one position taller and intersects considerably more of the forty lines.
Strategy
Because Wilds cannot reach reel 1, a screen full of expanded Wilds still pays nothing unless a real matching symbol turned up on the leftmost reel. That one restriction is the quiet reason the base game feels flatter than the feature list suggests.
| Reels | 2, 3 and 4 only |
| Expansion | Full column — 4 positions |
| Substitutes | All except the two Scatters |
| Multiplier | None |
Star & Diamond Scatter Pays
How to Trigger
Three or more matching Scatters on the grid — position on a payline is irrelevant.
What Happens
Two separate Scatters run in parallel with the paylines. The Star pays for three of a kind. The Diamond pays for three, four or five of a kind across the reels. Neither is substituted by a Wild and neither needs to sit on a line, so they resolve independently of the forty-line structure the rest of the game runs on.
Values
Star: three-of-a-kind pay. Diamond: three, four and five-of-a-kind pays, scaling with count.
Variants
The same pair appears throughout the Crypto Crown line, with the exact values differing between the 10, 20 and 40-line builds.
Strategy
These are the base game's safety net. They fire on spins where the paylines produced nothing at all, which on a grid with no multipliers and no cascades is a meaningful share of them. Nothing you do influences them — but knowing they exist explains why the balance moves on spins that looked dead.
| Star Scatter | Pays for 3 of a kind |
| Diamond Scatter | Pays for 3, 4 or 5 |
| Payline Needed | No |
| Wild Substitutes | No |
Jackpot Game
How to Trigger
Random. It can open at the end of any spin, including one that produced no win.
What Happens
The reels give way to a board of 18 hidden spaces. You pick orbs one at a time to reveal what is behind them. Matching a jackpot awards it. Some picks upgrade the value you are working toward, pushing you up a tier. Picking a bomb ends the round on the spot with nothing. There is no way to trigger it deliberately and no combination of symbols to collect first.
Values
Four tiers — Mini, Minor, Mega and Grand — worth between 50x and 5,000x the bet.
Variants
The board runs across the whole Crypto Crown series. It behaves like a scratch card bolted onto a slot, and it is the only place the 5,000x maximum exists.
Strategy
Since you cannot influence when the board appears, the only decision that matters is the stake you are holding when it does. Every tier is a multiple of the bet in play at that moment — which makes cutting your stake during a cold run the one genuinely expensive habit in this game.
| Trigger | Random, any spin |
| Board | 18 hidden spaces |
| Tiers | Mini, Minor, Mega, Grand |
| Range | 50x to 5,000x bet |
| Ends On | Jackpot matched or a bomb |
Win Gamble
How to Trigger
Offered after any win worth 35x your bet or less.
What Happens
A 50/50 call on the outcome. Guess right and the win doubles; guess wrong and it is gone entirely. You can keep taking the call for up to five doubles in a row. Wins above the 35x threshold skip the offer and are simply paid out.
Values
Doubling per correct call, up to five consecutive doubles from a qualifying win.
Variants
None. It's a single binary call — no partial gamble, no half-collect.
Strategy
Five correct calls in a row is the arithmetic behind the headline figure, and it's exactly as unlikely as a coin landing the same way five times. Used on a small win you would not mind losing, it is fine entertainment. Used as a strategy, it is the fastest way to turn a decent spin into nothing.
| Eligible Wins | Up to 35x bet |
| Odds Per Call | 50/50 |
| Max Doubles | 5 in a row |
| Partial Collect | No |
There Is No Feature Buy Here
Worth stating plainly, because the Crypto Crown line is inconsistent about it. Some builds in the series carry a paid spin — the ten-line version has one that guarantees Wilds on the next spin for a fixed cost. Crypto Crown 40 does not. There is no button that skips a cold run and no price you can pay to reach the jackpot board.
That is arguably the right call for this design. A feature buy only makes sense when it purchases access to something with a defined value, and the board here triggers at random rather than through any combination you could sell. Buying Wilds would buy you paylines on a grid with no multipliers — which, on the sibling title, is exactly the awkward maths that makes its Feature Spin hard to recommend.
So the practical shape of a session is simple: pick a stake you are content to hold, spin at it consistently, and let the Scatters cover the quiet patches. The board arrives when it arrives, and the only thing you controlled was what it was worth.
