Prices first, because that is the actual question. Gambonanza is $14.99 on Windows and $5.99 on other platforms. If you are buying on anything other than Windows, the value argument is close to over before it starts.
What you are buying is single-player roguelike chess. No multiplayer, no ranked ladder, no PvP. If any of those were part of your expectation, that matters more than anything else on this page.
THE HONEST VERDICT
Buy it if you like roguelikes where a single decision compounds across a run, and you are comfortable with chess pieces rather than chess matches. Skip it if you want competitive play, or if you dislike runs that can end from a board state you did not see coming.
What Is Actually in the Box
The content volume is the easiest part to judge, because it is countable.
Around 200 Gambits. These are the rule-breaking powers that define every build, and they are the reason runs differ from each other. You can hold 5 at a time, so the pool matters more than the cap.
53 Steam achievements, and a Collection of around 200 entries across six categories: Gambits, Pieces, Tiles, Enemy Modifiers, Bosses and Strains. The Collection is a progression metabasis, not just a checklist, because what you unlock changes what future runs can offer you.
6 difficulty tiers, unlocked after your first clear, with negative modifiers stacked on as you climb. The top tiers also hide a sixth boss beyond the standard five checkpoints.
| What you get | Detail |
|---|---|
| Gambits | Around 200, hold 5 at a time |
| Achievements | 53 on Steam |
| Collection | Around 200 entries across 6 categories |
| Difficulty | 6 tiers, unlocked after first clear |
| Platform | Steam Deck Verified since 1.5.0 |
| Multiplayer | None, single-player only |
The Case For Buying
The strongest argument is that it is not really chess. This trips people up in both directions, so it is worth being precise.
You move chess pieces, but the objective is to capture every enemy piece, not to checkmate a king. The enemy king is just another piece. You lose when all your pieces are gone. That single change removes most of the chess knowledge barrier while keeping the spatial reasoning that makes chess satisfying.
Who it clicks for
If you bounced off chess because of opening theory and memorised lines, this is a different game wearing chess clothes. If you bounced off deckbuilders because the cards were abstract, the board gives those choices a physical shape.
The beginner guide covers what the first few runs look like if you want to see the shape of it before committing.
The Case Against
Three honest reasons to skip it, in order of how often they apply.
- You want multiplayer. There is no ranked mode and no PvP. The game is single-player, full stop.
- You want a bounded session. A run is 25 games, but the length of each game floats with the board state, so you cannot reliably say how long a run takes. The run length breakdown explains why.
- You dislike losing to hidden state. Several bosses attack information rather than material: one hides the enemy formation during staging, another shuffles and hides your own pieces. You can prepare for these, but you cannot scout them.
The one that actually annoys people
Bosses that remove information. If you like games where perfect play is always available, Judit Polgeisha and M3CH4GNU5 C4RL53N will frustrate you, because they take away the board knowledge you are using to make decisions.
Where the Platform Difference Matters
Gambonanza became officially Steam Deck Verified in 1.5.0. That is a real signal, not marketing: Valve checks input, legibility and stability on the handheld, and 1.5.0 also shipped a UI and text revamp aimed squarely at small screens.
Buy it where it is cheaper
At $5.99 on non-Windows platforms versus $14.99 on Windows, the same game costs a quarter as much elsewhere. If you have a Deck or a handheld and the price is the deciding factor, that gap is the deciding factor.
The Steam Deck settings guide covers which toggles to change before your first handheld run, since Verified does not mean the defaults suit everyone.
How Much Game 53 Achievements Actually Is
Achievement count is a weak proxy for content, so it is worth saying what it does and does not imply here.
Read it as breadth, not hours
53 achievements across Gambits, Collection categories and difficulty tiers means there are many distinct things to do. It does not tell you how long each takes. Combined with around 200 Collection entries and 6 difficulty tiers, the shape is broad rather than deep.
Several achievements were also failing to register before 1.5.0, and that patch fixed a batch of them. If you met a condition earlier and got no credit, re-running the condition should now register it.
What Decides It
One question settles most purchases: do you want a roguelike where the board is the deck? If yes, this is one of the few games doing that, and the $5.99 price on non-Windows makes trying it cheap. If no, no amount of content volume will change the answer.
