The short version

Jewels is a line-based video slot: pick a bet between the listed minimum and maximum, spin the 5x8 grid, and matching jewel symbols pay out along any of the 28 fixed paylines. Wilds substitute for regular symbols on those lines, and a risk/gamble round is available after a win if you want to double it.

  • No cluster pays or cascading wins — this is a straight line-pay slot
  • Wins are read left to right across the 28 preset lines
  • The gamble feature is optional and separate from the base spin

Reels, lines and how a spin resolves

Jewels departs from the usual 5x3 template with a taller 5x8 layout, meaning each of the five reels shows eight symbol positions once a spin stops. Across that larger frame, 28 fixed paylines are checked for matches, so the game plays like a traditional line slot rather than a ways-pay or cluster-pay title — there is no evidence of cascading reels or symbol removal after a win.

Symbols are built entirely around a jewelry and gemstone theme, set against a space-styled backdrop. Diamonds sit at the top of the pay hierarchy, with rubies, emeralds and sapphires filling the mid and lower tiers. There is no indication of card-rank symbols (10 through Ace) or fruit icons in the mix, which keeps the reels visually focused on cut and colour rather than mixed iconography.

A wild symbol substitutes for regular paying jewels across active lines, helping to complete combinations that would otherwise miss. A scatter symbol is also confirmed as part of the feature set, though its exact visual and whether it pays independently of triggering something else are not detailed in the available material — worth keeping in mind if you're specifically chasing a scatter-triggered round.

After a win lands, Jewels offers a risk/gamble (double) option, a familiar mechanic in AGT Software's catalogue that lets a player stake the win amount on a separate double-or-nothing decision before it's collected. This sits outside the main paytable and is entirely optional on each win.

Betting runs from a minimum of 0.28 up to a maximum of 140 per spin in the currency your casino displays, spread across the 28 lines. The game is rated medium volatility, which points to a reasonably even mix of smaller frequent hits and occasional larger ones, without the extreme swings associated with high-variance titles.

Questions about playing Jewels

Do all 28 paylines have to be active on every spin?

Jewels is documented as a fixed-line game, so the 28 paylines are checked as a set on each spin rather than being individually toggled on or off.

What does the risk/gamble feature actually do?

After a win, you can choose to stake it on a separate double-or-nothing round instead of collecting it; the exact format of that gamble isn't detailed in available documentation, only its presence as a feature.

Can the wild symbol appear anywhere on the 5x8 grid?

The wild is confirmed to substitute for regular jewel symbols on active lines, but the sources don't specify whether it's restricted to certain reels or positions within the eight-row layout.

Does the bet range change if I play on mobile?

No separate mobile bet range is documented; the game runs on HTML5, which supports play across desktop and mobile browsers using the same 0.28 to 140 range.
