Four look-alike names, one very different engine. Type the bare phrase into a search box and you will meet chest-themed slots from four different studios, plus a healthy number of video-game wikis that have owned the words for years. The game this site covers is the Endorphina release from 3 September 2026, built on a 4x3 grid of twelve independent reels, and the point of this page is to say exactly where it sits among its neighbours.
What makes 3 Golden Chests hard to copy#
A look-alike title would have to reproduce two structural choices before it felt like this one: twelve independent reels on a 4x3 frame, and three chests that each count the same board in a different way.
The first choice is the grid. Four reels and three rows, but with every one of the twelve positions turning as its own reel, which means the screen resolves as a picture instead of as a left-to-right sequence. That, in turn, forces the second choice: scatter pays, because there is nothing to line up. A symbol counts where it lands, and the prize it carries is printed on its own face for the stake you selected. Those two moves together are what give the base game its unusually calm reading.
The second choice is the three-chest layer. BOOST, MYSTERY and COLLECT are not three names for the same bonus symbol; they are three different arithmetics. BOOST adds its own 1x, 2x, 3x, 4x, 5x, 7x or 10x the total bet to every BONUS symbol on the grid and then leaves. MYSTERY holds a value face down until the round ends and reveals MAX at 100x, MID at 50x, MIN at 20x or a regular 7x or 10x. COLLECT adds the board up and keeps the total as an extra prize, leaving every symbol it counted holding its own money. Each chest lights up at random and independently of the symbols that opened the round, so which combination you get is the main source of variety between one bonus and the next.
Around those two choices sit a set of decisions that are easy to describe and hard to beat: an entry earned on the reels rather than bought, a round with a visible shape at 3 attempts and 12 positions, and four fixed jackpot tiers whose value you can price before you spin, topped by ULTRA at 1,000x the total bet. Priced at a 10 total bet that ladder runs 200, 500, 1,000 and 10,000; at a 100 total bet it runs 2,000, 5,000, 10,000 and 100,000, with the round ceiling of up to 1,400x sitting above both. The features page takes each of them apart.

How the head-to-head reads#
Mighty Crown: Empire of Gold earns the side-by-side above because it is trying to do something genuinely similar: a compact golden grid with a Hold and Win round on top, built by a different studio with a different set of instincts. The short version of the difference is where each game puts its complexity.
3 Golden Chests puts it above the reels. The grid is simple and the layer that varies is the chest row, which loads the bonus differently every time. Wazdan’s title keeps a more conventional line structure and lets its own settings and volatility options carry the variation. Neither approach is better in the abstract; they suit different evenings.
The other visible difference is the jackpot model. Fixed tiers, as used here, mean the value of the thing you are chasing never moves. That is a real comfort on a High volatility game, because the arithmetic of a long session is stable even when the results are not. The full comparison, dimension by dimension, is on the head-to-head page .

Sorting the names out#
Treat the confusion in the search results as navigation rather than as a nuisance, because each of those titles tells you something about what you might actually want.
If the chest theme is what drew you in, the other four titles deliver it in their own ways, and any of them may suit you better on a given evening. If it was specifically the Hold and Win structure, the Hacksaw release is the closest by genre, while Mighty Crown: Empire of Gold is the closest by shape, which is why it gets a full page of its own here. And if it was Endorphina’s style, the studio’s own Fortune Chests and Fortune Chests Dice are worth a look, with the important caveat that they are separate games: none of the numbers on this site carry across to them.
There is one measurable difference behind all that naming, and it is the reason this page keeps coming back to the engine rather than the artwork. A slot with five fixed lines resolves a spin along those lines; this one resolves twelve independent positions at once and pays by scatter, then holds the money on the symbols until the Bonus Game collects it. Anything with a similar cover but a line structure underneath will feel different from the first spin, whatever the chests on its logo suggest.
One practical note on names. Because the bare phrase brings results from entirely different worlds, keep the qualifier when you search: adding “slot” or “Endorphina” puts you in the right catalogue immediately. The same habit helps in a casino lobby, where several of these titles can sit a few tiles apart.
The studio itself is a reasonable reason to keep exploring its catalogue. It works under an MGA supplier licence, is registered as a gaming-related supplier in Ontario and holds an Alberta licence as its fifty-ninth regulated jurisdiction, which is a track record worth something when you are deciding whose games to try next. Our Endorphina page has the full picture.
What to compare when you try an alternative#
If you do go looking, check five properties in any candidate, because they are the ones that decide how a session feels rather than how it looks.
- How the bonus is entered. Earned on the reels, as here, or bought from a cart. That single difference changes how a budget is spent.
- Whether the round has a visible shape. Three attempts and twelve positions tell you how much room is left; a round without a counter does not.
- Whether the jackpots are fixed or pooled. Fixed tiers can be priced before you spin: 20x, 50x, 100x and 1,000x the total bet in this game.
- Where the prize values live. Printed on the symbols here, which keeps the maths in front of you rather than behind a menu.
- What the published rhythm is. High volatility with a 2.78% hit frequency, about one spin in 36, describes concentrated settles; a candidate with a different profile will feel different even at the same return.
Run those five questions past any chest slot you find and the shortlist gets short very quickly.

If what you like is…#
Pick by what keeps you playing, rather than by the artwork. Three common preferences, and where this game lands on each.
- A high ceiling and a real wait for it. 3 Golden Chests is rated High volatility with a 2.78% hit frequency and a ceiling of up to 1,400x the total bet, with the provider’s material going as far as 1,500x. If that profile suits you, the RTP page prices it at every stake. If you want something steadier, a line game with frequent small wins is the better fit.
- Knowing what you are chasing. The four tiers here are fixed multipliers: ULTRA at 1,000x, MAX at 100x, MID at 50x and MIN at 20x the total bet. Nothing depends on a shared pool or on how recently someone else won, which is the main reason to prefer this one when you like pricing what you chase.
- A quick, self-managing session. AUTO and TURBO sit on the bottom bar, the grid reads in a glance and an unfinished round is kept for seven days, so a short window is a usable session and an interrupted one costs nothing. The strategy page has a stake plan that fits that pattern.
There is a fourth preference worth naming, and it is the one a spec sheet cannot show: how much you enjoy watching a board fill. This game is built around that feeling. The counter resets with every new symbol, the twelve positions are few enough to be countable, and the last few spins of a productive round carry real tension because a complete board is the ULTRA condition, a fixed 1,000x the total bet. A board of twelve is small enough to hold in your head while it fills, which is exactly what gives those final attempts their weight. If that particular pleasure is what you are shopping for, the alternatives are worth trying, and this is the shape that produces it most directly.
Whichever way you lean, the cheapest way to settle the question is to look. Load the demo and watch one round of the Bonus Game open: the three chests, the attempt counter, the reveal at the end. One complete round will tell you whether the alternatives are worth chasing at all, and the slot hub has everything else about the game in two screens.
