For a flat, rules-heavy card game wrapped in an app-style interface, a TypeScript rules core with React Native can be a sensible alternative to Unity or Godot. It makes it possible to test game logic apart from the screen and share that logic across games—but the team must build and maintain interaction, rendering, accessibility, and native-app details itself. Unity and Godot offer documented 2D workflows; neither is automatically the better choice for every card game.
What the TypeScript approach looks like
In an October 5, 2026, account, the developer of Decks described an iOS app with fourteen games at that point: nine solitaire games and five puzzles. Its table was rendered with React Native Skia, while menus, settings, sheets, and rules pages used React Native views. The project separated a pure TypeScript game core from the mobile app and design tokens. The developer’s account is a case study, not a controlled comparison of engines.

The key distinction is that “my own engine” does not have to mean rebuilding every part of a game engine. Here, the custom work centered on a reusable rules system and a card-table presentation, using an app framework for the surrounding product. Game rules were represented as data interpreted by shared code. The developer says that core could enumerate legal moves, support hints and “no moves left” checks, and run tests and bots without relying on the rendered screen. Time and random input were passed into the core rather than accessed through platform APIs.

When a custom TypeScript stack is a good fit
- The visuals are relatively simple. The developer judged flat cards and straightforward transforms sufficient for this app, rather than needing a full 3D workflow. That is a project-specific judgment, not a rule that card games never benefit from an engine.
- Rules and repeatable testing matter more than built-in game tooling. A rules core that runs without a screen can be tested with seeded random input and recorded move sequences. The developer says bugs could be captured as a seed plus moves and retained as regression cases.
- You are building several games on shared foundations. In the developer’s account, Yukon shipped as the app’s fourteenth game without changes to the engine or rules language, using existing undo, hints, saves, and rules text. This illustrates the potential payoff of shared architecture; it does not guarantee that a new game will require no engine changes.
- The product is also an app. Settings, accessibility text sizing, menus, purchases, and other mobile interface needs can sit alongside a custom-rendered table. The author used React Native views for the app UI and reports implementing StoreKit 2 purchases through a small Swift Expo module.
- Your team already works in TypeScript. The developer used it for app code, the rules core, tests, and build-time tools. React Native also documents TypeScript setup at its TypeScript guide.
What you take on without a game engine
A custom stack transfers responsibilities that an engine-oriented workflow may otherwise provide or organize. In this project, the developer built hit testing and gesture handling, managed the per-frame workload, handled native dependencies, and had to consider how a canvas-based table would work with accessibility technologies. The author described the Skia canvas itself as inaccessible to VoiceOver as a semantic table; surrounding native views did not make the canvas equivalent to a structured table.
#1 Best Overall
- Play a card from your hand, and place a chip on a corresponding space on the game board - when you have five in a row, it’s a SEQUENCE
- Each player or team tries to score the required number of five-card SEQUENCES before their opponents
- Easy enough for children, challenging for adults!
- Exciting gameplay develops STEM skills like strategy
- Includes 1 Folding Game Board (19.75" x 15.25"), 2 Decks of SEQUENCE Playing Cards (2.25" x 3.5"), 135 Playing Chips (50 Green, 50 Blue, 35 Red), and Complete Instructions
The developer also reported that conditional transforms across 52 cards caused a touch-related crash, and that a Codebreak session’s frame rate fell from 118 to 41 before idle work and repeated font creation were identified as contributors. The first drag implementation reportedly triggered about 3,120 checks per second for 52 cards. These are observations from one app, not benchmarks against Unity or Godot and not predictions for another project. They do show why hit testing, animation work, gesture code, and rendering need deliberate performance budgets.
There were also maintenance costs beyond rendering. The author reported native dependency version friction and a custom rules language that repeated expressions and lacked a way to name subexpressions. A rules abstraction can reduce duplicated game logic, but it becomes another system to design, debug, and evolve.
Rank #2
- SCRABBLE CARD GAME: Slam is a little different than the traditional game of Scrabble. Slam is very fast-paced and everyone can play at once
- THE PLAY: Choose a 4 letter word to start play then deal out the remaining cards as evenly as possible. When everyone is ready - the action begins. Any player can play 1 letter card on top of the cards on the table to make a new word. For example: "CAKE" becomes "BAKE" which is turned into "BIKE" then switched to "LIKE" and so on
- THE WIN: Players continue placing cards as quickly as possible forming new words until someone plays their last card for the win
- TRAVEL SIZED: It's a card game - of course you can fit it into your carry-on or even a purse
- QUICK GAMEPLAY: Given that game play is very fast paced and goes by quickly, Scrabble Slam works well in between longer gaming campaigns on game night
How Unity, Godot, and TypeScript compare for this decision
| Decision factor | TypeScript core and app framework | Godot | Unity |
|---|---|---|---|
| Rules and tests | The Decks developer chose a pure TypeScript core that could run apart from the screen and be tested with recorded inputs. This is an account of that implementation. | The cited official tutorial teaches a complete 2D game workflow; it does not compare rules-test architecture with the Decks implementation. | The official 2D documentation covers 2D projects and tools; it does not establish how a particular project’s rules should be structured. |
| 2D rendering and physics | The author considered simple card visuals and transforms sufficient, and used Skia for the table. | Godot’s official first 2D game tutorial demonstrates a 2D development path. | Unity’s official 2D documentation describes sprites, Tilemaps, and 2D physics workflows. |
| App interface and accessibility | The developer combined React Native views with a Skia canvas, but reported that the canvas was not exposed as a semantic VoiceOver table. | The cited tutorial alone does not settle how a complete app’s interface or accessibility should be implemented. | The cited 2D overview alone does not settle how a complete app’s interface or accessibility should be implemented. |
| Work the team owns | In the case study, the developer owned hit testing, gestures, frame-work constraints, native modules, and compatibility work. | The documented editor and 2D workflow may suit a team that wants an engine-centered process; assess it against the project’s actual requirements. | The documented editor and 2D tooling may suit a team that wants an engine-centered process; assess it against the project’s actual requirements. |
The official documentation establishes that Unity and Godot have 2D workflows; it does not show which option will perform better, ship smaller, or require less effort for your game. Choose based on the rendering and physics your project needs, target platforms, team experience, interface and accessibility requirements, and how much engine-level work you want to own.

How to make the choice
- Describe the hardest part of the game. If it is a rules system shared across many games, a screen-independent core may be valuable. If it is complex physics, elaborate animation, or a heavily editor-driven scene workflow, evaluate the engine features you will actually use.
- List the whole product, not just the playfield. Include menus, settings, accessibility, purchases, saves, and platform integration. A table that looks simple can still sit inside a demanding mobile app.
- Prototype the riskiest interaction. For a custom canvas, test card selection, dragging, hit testing, and accessibility early. For an engine, build a representative slice of the intended 2D workflow rather than choosing from feature lists alone.
- Test rules independently if reuse and correctness are priorities. Decide whether seeds, explicit time and random inputs, and replayable move sequences fit the game. Keep the rules layer separate only if that separation has practical value for the team.
- Estimate ongoing ownership. Count the work required to maintain gesture behavior, frame budgets, native integrations, and compatibility alongside game features. Compare that with learning and maintaining the engine workflow you are considering.
How much weight to give the project figures
The developer reported about 1,650 game-core tests and about 5,000 app tests during the 1.0.3 cycle, as well as 855 scenes across five languages at the largest reported accessibility text size with zero reported violations. The same account put the app at about 59 MB. These are self-reported project figures from the October 5, 2026 article, not independent measurements or evidence that another stack would produce similar results.
Rank #3
- Your goal: try to collect as few points as possible over several rounds of play as quickly as possible by skilfully uncovering, exchanging and collecting playing cards, as few points as possible. But this can only be done as long as a player has not revealed all their cards, otherwise the round of game ends. So be careful, keep an eye on the game and the players
- Great fun for your friends and family. Skyjo is a fun card game that is great fun for children and even large game friends (adults). The card game is very suitable for short games in between and is also an enrichment for a sociable and beautiful game evening.
- Learn playful: calculate - learn to add up to 100 two-digit numbers. Estimate - Get a sense of probability. Concentration - Track game sequences and watch players and their actions.
- Fast game start. Simple, easy-to-understand game principle. Short game instructions with pictures. Ideal for a short game in between as well as as as a base game for fun and exciting game evenings. The game is round-based and can be played flexibly in time.
- Number of players: for 2 to 8 players. Age: from 8 years. Playing time: approx. 30 minutes. Languages: German, English, French, Spanish, Italian. Material: 150 playing cards, 1 game pad, 1 game instructions (English language not guaranteed). Made in Germany.
The most useful conclusion is about fit, not a universal ranking: a deliberately small custom stack can serve a flat card table and a multi-game rules architecture, provided the team is prepared to own the surrounding engineering. For a project that needs engine-centered 2D tooling, Unity and Godot both have documented paths worth evaluating.
