Classic Reels, Modern Crown Mechanics
In 3 Crowns: Coin Hunt slot, fruit imagery is used in a way typical of a standard fruit machine, but with a greater focus on coloured symbols. Thus, the 20-payline base game serves as the framework upon which the feature set becomes quite complex with the introduction of the Crowns.
In the standard reels, fruit imagery is complemented by standard BAR symbols, bells and diamond symbols. There is also the addition of a Wild symbol, which substitutes for any combination apart from Bonus symbols and which is only available on reels 2-5 within the Main Game.
Red, Purple, Green and Gold symbols form part of the feature set of 3 Crowns Coin Hunt. They unlock bonuses via the extra round. This is one of the key features of 3 Crowns: Coin Hunt, whose design is based on classic casino slots.
| Element | Role in the game |
|---|---|
| 5×3 reels | Main game structure |
| 20 paylines | Fixed win-line format |
| Fruits, BAR, bell, diamond | Classic reel imagery |
| Wild | Substitutes for regular symbols except Bonus symbols |
| Red, Purple, Green symbols | Can trigger corresponding Crown boosters |
| Gold symbols | Appear during the Bonus Game |
Why Three Crowns Matter
The Red, Purple and Green symbols are not mere stylistic variants of the same bonus. In fact, each colour stands for a particular Crown which affects the Bonus mode differently: Red alters the size of the game area, Purple introduces the collecting principle, and Green alters the number of spins.
Red Crown Adds Reels
The Red one is connected to the Red Crown and triggers the Double Reels booster. When this booster is turned on, an additional playing area is added to the game right before the start of the Bonus game. These two areas then spin separately while the feature lasts. When the feature ends, the game sums the winnings from both areas. Therefore, the Red Crown not only adds another symbol or prize value but alters the very principle of the feature.
Purple Crown Collects Values
Purple Trigger unlocks the Purple Crown and the Collector Booster. Collector Booster can be attached to any randomly selected blank cell in the field of play. It collects values and jackpots marked by all Bonus symbols found in that field of play. Once the collection phase ends, the Collector turns into the regular symbol. Purple Crown alters how existing values are processed in the field during the feature. It does not add a new field like Red Crown; instead, it brings the collection mechanic to the feature.
Green Crown Adds a Spin
Green Trigger unlocks the Green Crown and the Extra Spin Booster. While active, this Booster adds one extra spin in the Bonus mode, so that's four spins total. Thus, the only difference between the three colours is mechanical: Red adds more room for gameplay through Double Reels, Purple adds the Collector, and Green adds an extra spin in the feature. None should be considered better, since these Boosters alter different parts of the same extra round.
When Crown Features Combine
The Bonus mode could be activated with one, two or all three Crown boosters. This makes it possible for the modifiers to work in interaction inside one Bonus game, instead of working separately as three different bonuses. Gold Bonus symbols and the Collector may occur on the reels. Bonus symbols could hold any amount of money or MINI, MINOR or MAJOR jackpots. Collection of 15 Gold symbols gives the player the Grand Jackpot.
The Double Reels modifier alters the condition for achieving the grand jackpot even more. Because the Red Crown doubles the game field into two separate game fields, the product sheet indicates that it becomes possible to get two Grand Jackpots when the Double Game booster is active. From a mechanics standpoint, this interaction is the key difference. The distinguishing feature is not just the existence of three Crown boosters, but the possibility of their combination inside one Bonus game.
See the Crown Features in Action
On page 2 of the Evoplay product sheet, screenshots show the change from the classic base reels to the Crown-based feature states. Some important details that one can notice are the colouring of symbols, Double Reels, Collector and the modified Bonus mode.
Visual examples highlight the structural distinction between the Main Game and the feature system. In the first case, we see classic fruit-slot elements, while in the latter, there is additional emphasis on Crowns, Gold symbols, and game-field modification.
Three Crown Slots Compared
The crown theme doesn't operate in the same mechanical way across every slot that features a Crown theme. 3 Crowns: Coin Hunt game, 3 Jewel Crowns, and Crown Coins are all games that feature a royal or Crown theme, and each uses different mechanisms to do so. Therefore, the comparison will be more relevant in terms of mechanics.
| Game | Developer | Layout | RTP | Crown/Coin Role | Main Bonus Concept |
|---|---|---|---|---|---|
| 3 Crowns: Coin Hunt | Evoplay | 5×3 | 96.31% | Three coloured Crown boosters | Combinable Bonus game modifiers |
| 3 Jewel Crowns | 3 Oaks Gaming | 3 reels | 96% | Crown Metres | Free Spins modifiers |
| Crown Coins | Endorphina | 3×3 | 96.06% | Coins / Royal Coin | Royal Treasury |
The figures and mechanics used by Evoplay are found in the product sheet. Information about the two games being compared is in the content brief provided.
3 Jewel Crowns
3 Jewel Crowns by 3 Oaks Gaming was launched in June 2025. This game uses three Crown Meters for Green, Red, and Blue Crowns. The bonus mechanics of this slot involve seven Free Spins along with three modifiers like Extra Spins, Jackpot, and Double Reels. These elements can be activated simultaneously, and the Wild element may include an x2 or x5 multiplier.
The provided information also includes jackpot progression values: Minor from x25 to x50, Major from x100 to x250, and Grand from x1,000 to x5,000. Under this scheme, Crowns build and modify the Free Spins feature instead of serving as the Bonus-symbol mechanic, similar to Evoplay.
Crown Coins
Endorphina’s Crown Coins incorporates the 3×3 reel configuration, features five fixed paylines, has a 96.06% RTP, and has a Medium-High volatility level. The official bet spread for this slot is €0.05–€80. The game revolves around the Royal Treasury, Gold Coins, and a Royal Coin, offering jackpots up to x1,000. Moreover, this list includes a Risk Game feature.
This comparison shows three different approaches to this theme. 3 Jewel Crowns makes use of Crowns to create Free Spins modifiers. Crown Coins creates the royal idea through coins, accumulating Treasury Bonus and jackpots. Finally, 3 Crowns: Coin Hunt uses three coloured Crowns as Bonus mode modifiers.
Free Play Before Real-Money Play
The 3 Crowns: Coin Hunt demo may come in handy if you want to see how the feature works without losing any of your own money. Specifically, you can test free play mode and see the difference in Crown colours, as well as the effect of various boosters on the Bonus game.
Elements to pay attention to:
- Wild appearance on reels 2-5 in the Main Game;
- Red, Purple and Green Crowns' actions;
- Bonus mode sequence;
- positioning of Collectors;
- stake settings;
- how Double Reels increase the playing field.
In this case, free play is especially helpful, since the three Crown types look alike and work differently. Watching their actions will make you notice the differences better than just reading their names.
The demo cannot give you a hint at future winning chances with real cash. Neither does practising increase the chances provided by the game's RNG. Therefore, learning about a feature is not the same as gaining an advantage.
RTP and Game Profile
Game 3, Crowns: Coin Hunt has an RTP of 96.31%, medium-high volatility, and 16.31% hit frequency. The stake range is from €0.10 up to €75. According to Evoplay, the Bonus mode appears once every 109.87 spins. According to the game sheet, maximum payouts on 500 million spins are x705.5 in the Main Game and x7,324 in the Bonus game. Additionally, maximum win amounts are specified as €549,300 and $732,400. This information provides the mathematical basis for feature creation.
Bonus Buy Changes the Entry
To play 3 Crowns: Coin Hunt, , the Bonus Buy feature offers direct entry to the Bonus mode and lets you start with one, two, or three boosters. This is confirmed by the game's product sheet. Thus, the key difference between the two features is how you enter the Crown system. In contrast to the regular game, where players need to get extra symbols Red, Purple, or Green to enter the Crown system, the Bonus Buy feature offers immediate entry with certain modifiers. This feature only provides access, and it provides no information about the cost, RTP, or improved odds of winning.
What Defines 3 Crowns: Coin Hunt?
The distinction of the 3 Crowns Coin slot compared to the regular fruit slots lies in the juxtaposition of the traditional reel setup with the customisable bonus scheme. The main game remains true to its classic 5×3 reel layout, 20 paylines, and fruit-machine-themed symbols. The bonus features include three unique mechanical Crowns, which can expand the playing field, accumulate values and jackpots, or multiply the number of spins in the Bonus mode. The interaction of the boosters makes the Crown system the game's main structure.
