Splendor Duel expansions

The short answer, and the verified specs

• Splendor Duel - The Counterfeiters -- 2 players, 30 minutes, ages 10+. Bruno Cathala and Marc Andre, Space Cowboys, released 08/2026. Requires the Splendor Duel base game.
• Contents: 4 purple Glassware tokens, 17 Counterfeiter cards, 8 new Royal cards, 1 rulebook.
• It is the ONLY expansion Space Cowboys lists for Splendor Duel. Its own Splendor Duel page links exactly one expansion, and this is it.
• Two modules in the box. The Counterfeiter cards and Glassware tokens are one; the eight Royal cards are the other. They can be used independently.
• Splendor Duel itself -- 2 players, 30 minutes, ages 10+. Space Cowboys, 2022. Built for two, and you need it to use any of the above.

How we judged whether an expansion is worth it

Three questions, applied in this order, and they are the same ones we use on the 7 Wonders Duel expansions.

First: does it change a phase you already play, or does it bolt a new subsystem on top? Expansions that deepen something familiar tend to get used every game. Expansions that add a separate layer with its own cards, tokens and timing tend to get tried twice and then left in the box. This is the single best predictor of whether an expansion earns its shelf space, and it is the question this one splits on.

Second: how many plays of the base game do you have behind you? An expansion is a depth purchase. It is almost always the wrong thing to buy alongside a base game, because you cannot yet tell which part of the base game you want more of. If you have played Splendor Duel fewer than ten times, the honest recommendation is to keep playing it.

Third: does it cost you anything? Not price -- expansions in this bracket are cheap. The real cost is complexity added to a game whose appeal was that it was tight and quick, and in this case there is also a specific, physical cost to the base game's central mechanism that the next sections get into.

First: do not buy a Splendor expansion by mistake

This is the most practically useful thing on this page, because the names are genuinely confusing and the wrong box is the same price as the right one.

Space Cowboys publishes two games here. Splendor is the original, listed at 2-4 players. Splendor Duel is a separate standalone game, which the publisher describes as an original 2-player game in the Splendor universe -- not an expansion to anything.

Each has its own expansions, and the publisher files them separately. Under Splendor sit The Silk Road and The Sun Never Sets. Under Splendor Duel sits only The Counterfeiters. Both Splendor expansion listings state that they require the Splendor base game, and the publisher nowhere says that any Splendor expansion works with Splendor Duel.

So if you own Splendor Duel and you are shopping for more of it, The Counterfeiters is the only box that applies. Searching a retailer for "Splendor expansion" will surface The Silk Road and The Sun Never Sets high up, both of which are for the 2-4 player game, and neither of which will do anything for your copy of Duel.

What is actually in the box

It is a small box, and its contents are worth reading as two separate purchases that happen to be bundled.

The Counterfeiter module is 4 purple Glassware tokens plus 17 Counterfeiter cards. The Glassware tokens mix into the base game's shared token grid and are drafted like any other token, using the same adjacency rule. The Counterfeiter cards sit in a market of three alongside the Level III Jewel cards, and buying one costs at least one Glassware token plus gemstones. Once bought, a card gives either a one-time reward, an ongoing passive benefit, or an ability you can use once per turn by spending Glassware.

The Royal module is 8 new Royal cards, shuffled in with the base game's original four. They are claimed the same way the base Royals are. Two of them change the win threshold for whoever holds them -- 9 crowns, or 9 points in a single color, instead of the usual 10. The rest give one-time bonuses.

Note what is NOT here: no new board, no new victory condition for the game as a whole, and no change to the base game's three ways to win. This is a variety expansion, not a transformation, and its own publisher describes it in those terms -- new tactics and new abilities rather than a new structure.

The Counterfeiter module: how it works, and the honest case against it

This is the half the box is named after, and on the evidence available it is the weaker half. We have not played it, so here is the reasoning rather than a verdict dressed up as experience.

The structural problem is the Glassware tokens, and it follows from the base game's design. Splendor Duel's central tension is the 5x5 token grid: you may only take tokens that form an uninterrupted line, so every take is a decision about what you open up for the other player. The grid is the game. Adding four purple tokens to it means four spaces that would otherwise have held gems or Pearls now hold something only usable for one specific purpose.

The published review we are citing reaches exactly that conclusion from play: the reviewer writes that the Glassware tokens "actually get in the way" by occupying grid positions, and describes a pressure to buy a Counterfeiter card simply to have something to spend Glassware on. That is the failure mode a good expansion avoids -- new material that creates its own obligation rather than a new choice.

The cards themselves are reported as a mixed bag. Seven of the seventeen trade Glassware for discounts on particular gem colors, which overlaps what the base game's cards already do, and several of the remaining effects are described as situational. A few are genuinely interesting -- removing the ten-token limit at end of turn, using Glass in place of Pearls, taking two gems for a privilege instead of one -- but the reviewer's overall recommendation is to play without this module, which is an unusual thing for a review to say about the headline feature of an expansion.

Our position: treat the Counterfeiter cards as the optional half. If you buy this box, try them, and do not feel you have failed the expansion if you take the purple tokens back out.

The Royal cards: the half worth owning

The base game ships four Royal cards, and the same four come out every time. Over twenty or thirty plays that is the part of Splendor Duel that gets most predictable, because the Royals sit at the end of the crown race and you learn quickly what you are racing toward.

Eight more cards shuffled into that pool is the smallest possible fix for the biggest repetition problem the game has. It adds variety exactly where the game needs it, costs nothing in rules overhead, and the review we are citing singles it out as the part that works -- variety without much added complexity.

The two cards that lower a win threshold are the most interesting thing in the box. Needing 9 crowns instead of 10, or 9 points in one color instead of 10, sounds minor and is not: those are the thresholds both players are counting toward all game, and a card that quietly moves one of them for one player changes what the other person has to watch. That is a real addition to a game whose skill is largely in tracking how close your opponent is.

This is why the verdict at the top of this page is split rather than simple. If the Royal cards were sold on their own, we would recommend them to anyone with twenty plays behind them. They are not sold on their own, and the price of getting them is a box with a module in it you may well not use.

If you want an expansion that transforms a duel, buy a different one

Worth saying plainly, because a reader who wants their favorite two-player game to become a bigger game is not well served by this box, and there is a better-matched purchase one shelf over.

7 Wonders Duel: Pantheon is the clearest contrast we cover. It changes Age III rather than adding a parallel layer -- its Grand Temple cards replace the Guilds in the age you already play, so the expansion is unavoidable rather than optional, and it gives you a reason to look up from your own tableau. By the first criterion in this guide, that is what a strong expansion looks like, and The Counterfeiters is not that.

This is not a recommendation to buy a different game's expansion if you do not own that game. It is a recommendation about expectation: if "expansion" means transformation to you, The Counterfeiters will disappoint, and you should know that before you spend anything. If "expansion" means more variety in a game you already like, it delivers that through its Royal cards.

Who should buy it, and who should skip it

• Buy The Counterfeiters -- best for the pair with twenty or more plays of Splendor Duel behind them who have started to find the four base Royal cards predictable. The eight new Royals are the reason, and they are a genuine fix for the game's one repetition problem. Honest downside: the Counterfeiter module that gives the box its name is the weaker half, and its Glassware tokens take up spaces in the token grid that gems and Pearls would otherwise occupy.
• Buy Splendor Duel first -- best for anyone who does not own it yet. It is built for exactly two, runs 30 minutes, and has three live win conditions that can end the game on the spot. Play it ten times before you consider any expansion. Honest downside: it can stop before your plan pays off, which some pairs find annoying rather than exciting.
• Buy 7 Wonders Duel: Pantheon instead -- best for the reader who owns 7 Wonders Duel and wants an expansion that actually changes the game rather than adding variety to it. It rewrites Age III rather than bolting on a layer. Honest downside: it needs the base game, and it replaces the Guild cards in the endgame you already know, which not everyone wants.
• Skip all of it -- best if Splendor Duel comes out a few times a year. Nothing here fixes a game you are not playing, and an expansion bought on optimism rather than on plays is the most commonly wasted purchase in this hobby.
