Play RWB Gems

Three reels, BARs, 7s and shiny gems give RWB Gems a decidedly old school starting point, but Design Works Gaming hasn't left the mechanics in the past. The 3x3 grid uses 9 fixed paylines, while red, white and blue Gem Wilds feed separate feature piles as they land. Double Symbols can raise potential line payouts, and crossing the Bonus Line activates extra bonus game modifiers. We wouldn't call the setup complicated, but those gems are doing considerably more administrative work than their jewellery box cousins. 

RWB Gems keeps the visual side simple, with a black background, bright red, white and blue gems, metallic 7s and familiar BAR symbols. The three colour groups are more than decoration since each Gem Wild also connects to a matching pile used by the bonus system. Those piles rise beneath the main game and create most of the visual movement when gems are collected. 

Compared with more elaborate online slots, there's no character, landscape or narrative competing for attention. The design instead borrows from classic mechanical machines and adds a more modern feature display around them. The Bonus Line becomes an important visual marker, while the red, white and blue colour coding makes each modifier easy to follow. We appreciate the lack of clutter. Sometimes three reels don't need a cinematic universe attached to them. 

The regular paytable is built around BARs and 7s, while the Gem Wilds sit at the higher end. Because the game has only three reels, winning symbol combinations contain three symbols rather than four or five. 

• Gem Wilds: Red, White and Blue Gem Wilds substitute for the regular BAR and 7 symbols. Landing one also adds a gem to the matching coloured pile used by the Gem Feature. 
• Double Symbols: Special 2x versions of BAR and Gem symbols substitute for their corresponding regular symbols. Each Double Symbol involved in a potential line payout doubles that result, with the effect able to reach x8 when several appear on the same payline. 

Gem Feature 

Every Red, White or Blue Gem Wild landing on the reels adds a matching gem to the corresponding coloured pile. Each pile can rise until crossing the Bonus Line, and the colour that reaches that point determines which bonus modifier becomes active. 

The red pile activates More Multipliers, the blue pile activates More Wilds, and the white pile activates More Games. More than one pile can cross the Bonus Line on the same spin, allowing their respective modifiers to run together during the bonus games. Once the bonus round begins, additional features can't be earned from further pile progress. 

More Multipliers 

When the red gem pile passes the Bonus Line, More Multipliers becomes active for the 5 bonus games. Gem Wilds landing during those games are upgraded to 2x multiplier versions. 

The multiplier mechanic can also interact with More Wilds when both modifiers are active. Converted BAR symbols involved in that combined setup receive the multiplier treatment as well, giving the two bonus mechanics a direct connection rather than running as completely separate additions. 

More Wilds 

The blue pile triggers More Wilds after crossing the Bonus Line. During the 5 bonus games, Single BAR symbols are converted into special BAR symbols that leave behind Blue Gem Wilds when they land. 

If More Wilds and More Multipliers are active together, those converted symbols can also gain the 2x multiplier effect. The result is a bonus round with more substitution symbols on the reels and an additional multiplier mechanic attached to some of them. 

More Games 

Crossing the Bonus Line with the white gem pile activates More Games. Instead of the standard 5 bonus games, the round begins with 10. 

White Gem Wilds can extend the feature further because each one landing during the bonus games awards another bonus spin. The total number of bonus games can continue increasing in this way, subject to the game's stated feature limit. 

RWB Gems uses a compact 3 reel, 3 row layout with 9 permanently active paylines. Potential line payouts run from left to right across adjacent reels, beginning with the first reel. When more than one payline produces a result, those line amounts are added together. 

Only the highest potential payout is counted for each individual winning payline or symbol combination. The basic reel structure is therefore very traditional, but the Gem Feature adds progression outside the paytable itself. Wild gems contribute to coloured piles, Double Symbols can multiply line results, and the three pile based modifiers determine how the bonus games change once activated. 

Three previously reviewed titles stand out across online casinos for their classic symbols, jewel imagery or straightforward reel setups. 

• Super 7s: The emphasis on 7 symbols and a traditional slot presentation makes this the clearest match for RWB Gems on theme. 
• Joker's Jewels Wild: Gem and jewel imagery keeps the visual connection strong, while the familiar reel format gives both games an old school casino feel. 
• Joker's Jewels Cash: The jewel theme returns here as well, paired with a simple symbol set and feature mechanics built around a classic slot foundation. 

RWB Gems looks extremely traditional at first glance, which makes the feature system a pleasant surprise. We like how the three coloured Gem Wilds serve two jobs at once, substituting on the reels while also pushing their matching piles toward different bonus modifiers. That gives the small 3x3 grid more going on than the BARs and 7s initially suggest. 

The strongest part for us is the way More Multipliers, More Wilds and More Games can combine when several piles cross the Bonus Line together. The visual presentation is deliberately basic, so anyone expecting elaborate characters or cinematic sequences won't find much of that here. Still, the compact layout and connected gem mechanics make the design feel purposeful rather than merely nostalgic.
