3 Golden Chests

3 Golden Chests is a 4x3 slot from Endorphina, released on 3 September 2026, running on scatter pays at an RTP of 96.04% with high volatility. There are no paylines to follow and no wilds to wait for. The game is a coin-collection machine wrapped in a medieval castle, and the three chests named in the title sit above the reels doing the actual work.

Three Chests, Three Jobs

Across the top of the grid stand three treasure chests, each labelled and colour-coded: BOOST in fiery red, MYSTERY in green and COLLECT in purple. They are not decoration – they are the three things that can happen to the coins on your screen, kept in permanent view.

BOOST adds a prize to every bonus symbol on the reels, worth your total bet multiplied by 1x, 2x, 3x, 4x, 5x, 7x or 10x. COLLECT sweeps up the value of every bonus symbol currently showing and pays it as one figure, and it fires only once. MYSTERY turns into a prize of its own: MAX pays 100x the total bet, MID pays 50x, MIN pays 20x, and the ordinary results are 7x or 10x.

The Pile Feature And Hold And Win

The two features are stacked rather than separate. The Pile Feature is what puts the Boost, Mystery and Collect chests into play; the Hold and Win Bonus Game is where they are spent. The screenshots catch the transition clearly – the banner along the bottom of the reels reads “YOU WON THE HOLD AND WIN BONUS GAME!” while gold coins lock into place across the 4x3 grid.

Inside the round the coins carry plain cash values against a €10.00 bet: 10.00 is the common one, with 20.00, 30.00, 40.00, 50.00 and 90.00 appearing as the grid fills. Positions that have not yet landed a coin show the game’s own logo as a placeholder, so the progress of the round is legible at a glance – you can see exactly how many cells are still open.

The Jackpot Ladder

One screenshot shows the round in its upgraded state, and it is a different game. The castle interior has been replaced by a hoard of gold, three red hearts sit under the reels as the respin counter, and a full jackpot ladder has appeared down the left-hand side: ULTRA €10,000.00, MAX €1,000.00, MID €500.00 and MIN €200.00.

Against the €10 bet in that shot the ladder reads as 1,000x, 100x, 50x and 20x. The MAX, MID and MIN values match the Mystery symbol prizes exactly, but ULTRA sits an order of magnitude above them. The same screenshot shows a green question-mark tile and a purple coin worth €170.00 – a collected total rather than a single symbol value.

The Risk Game

Endorphina has kept its house gamble feature. A win can be taken to a card round showing CURRENT WIN against GAMBLE TO WIN at double the amount – one screenshot catches €750.00 offered up for €1,500.00. The dealer’s card is face up, four face-down cards are yours, and beating it doubles the total.

RTP, Volatility And The Ceiling

The 96.04% RTP is standard for the studio and sits just under the industry average. Endorphina rates the volatility as high, which fits a game with no line wins at all – everything arrives through the bonus, and the base game exists mainly to trigger it.

The ceiling is 1,400x. That is a modest number by 2026 standards and it is worth being clear about what it means here: a full grid of coins at their listed values is not going to reach it on its own, so the top result depends on the Boost multipliers landing on a well-populated board, or on the Ultra jackpot. It is a game with a low roof and a wide floor rather than the reverse.

Stakes And Presentation

Bets run from 0.1 to 250, a genuinely wide range. The interface is unfussy: BASE BET, CURRENCY and BET readouts along the bottom bar, with TURBO, AUTO and SPIN on the right.

The setting is a medieval castle in warm stone and heavy gold – carved pillars either side of the reels, a vaulted arch above the three chests, a red glow behind the grid. Because the reels carry only coins and the game logo, the screen stays readable even when it is full.

Who It Is For

This suits players who like hold-and-win games and would rather watch a grid fill with cash values than track paylines. The three named chests are a real design win: most collection slots hide their modifiers behind a random trigger, and this one keeps all three outcomes on screen throughout.

The reservation is the 1,400x ceiling, and the high volatility means the stretches between bonus rounds are genuinely quiet. What is on offer instead is a clean, legible bonus game with a four-tier jackpot ladder on top of it and none of the feature clutter this format usually carries.
