Jewels of Jupiter Hold and Win

Jewels of Jupiter Overview

Jewels of Jupiter: Hold and Win is a Kalamba Games slot on a three-by-three grid with 10 paylines, four prize plates and a published maximum win of 27,000x the bet – an extraordinary figure for a board with only nine positions.

Its buy menu is unusual too: three options, all giving the same three spins, differing only in the odds of what lands.

Theme and Graphics

The setting is Olympus from above – a red-tiled Mediterranean town on a hillside, thunderheads piling up behind it, lightning flickering at the edges of the frame. Trigger the feature and the scene moves inside a marble temple with a brazier burning at the back.

The reels stand between two fluted gold columns under a carved pediment, built as a temple facade rather than a frame. Zeus himself, white-bearded and wreathed in cloud, is the wild.

The symbols are cut gemstones – a red ruby, a green emerald, a purple amethyst, a blue diamond – with a gold laurel wreath above them and card letters beneath. All figures below come from demo play at bets of 10.00 and 30.00 EUR.

The Paytable

Three reels means every combination is three of a kind, and the line pays are correspondingly small. At the 30.00 stake the Zeus wild leads at 100.00 for three – that is 3.3x the bet.

The laurel wreath pays 50.00, the ruby 20.00, the emerald 15.00, and the amethyst and the diamond share a rung at 10.00 – a third of the stake for a complete three-symbol line.

So the best combination on the board returns three and a third times the bet, and the cheapest returns a third of it. On a paytable that flat, the lines exist to keep the reels moving rather than to pay anybody.

The demo confirms it: base results of 5.00, 40.00, 65.00 and 162.00 across the two stakes – the largest of them, a board with two Zeus wilds flanking a king, worth a little over five times the bet.

The Plates Are Fixed Cash

Here is a detail worth two screenshots. The four plates down the left read Maxi 10,000.00, Major 5,000.00, Minor 500.00 and Mini 200.00.

They read exactly that at the 30.00 bet, and exactly that at the 10.00 bet. The values do not move with the stake.

That makes them fixed cash sums rather than multiples, and the consequence is the usual one: at the 10.00 bet the Maxi is worth 1,000 times your spin, and at 30.00 it is worth 333 times. Raising the stake makes every plate on the screen relatively cheaper.

The Hold and Win Round

The feature clears the board to nine glowing blue orbs with a SPINS LEFT counter beneath them, and each orb carries a cash value.

The demo catches a full board reading 50.00, 80.00, 150.00, 180.00, 60.00, 110.00 and 110.00, with three spins still remaining and a 2,000.00 plate lit on the left.

Note what the BET field shows during that round: 1,000.00. That is the price the round was bought for, not the stake the prizes are calculated from – a trap worth knowing on any Kalamba title, because reading the plates against it would badly understate them.

The Buy Menu: Buying Odds, Not Spins

The BuyBonus panel offers three cards, and every one of them gives 3 hold and win spins. What changes is the wording above:

STANDARD CASHPOTS ODDS – 300.00. BOOSTED CASHPOTS ODDS – 500.00. HIGHEST CASHPOTS ODDS – 1,000.00.

That is an unusual axis. Most buy menus sell length or a guaranteed trigger; this one sells probability – the same three spins, with a better chance that what lands on them is worth having.

The pricing is steep for it: boosted costs 1.7 times standard, and highest costs 3.3 times. A TIER selector above the cards, set to 21 in the demo, scales all three. A Hyper Bet panel on the right adds a second lever, offering in one capture to activate more symbols – changing what can land rather than how many paths count.

RTP, Volatility and Max Win

The RTP is 94.36%, volatility is rated Medium, and the maximum win is 27,000x the bet.

The return figure carries the usual Kalamba caveat: the studio operates RTP ranges, so the same title ships in several configurations and the operator picks one. 94.36% is close to two points below the modern standard.

Medium sits oddly against a 27,000x ceiling. The explanation is the nine-cell board: rounds arrive and resolve quickly, orbs land often, and the balance moves in small steps – but the very top of the distribution requires a full board of high-value orbs on the highest-odds purchase, which is a vanishingly rare arrangement.

It is a handsome, compact game with a genuinely novel buy menu and a headline number wildly out of proportion to its grid. Worth playing at a small stake, where the fixed plates are worth the most.
