# Daker Online: how we built a multiplayer poker game in Unity > How we built Daker Online in Unity: a social card game for Android with 105 hands, six-seat tables and a WebGL demo. No real-money gambling. URL: https://overfuture.dev/en/products/daker-online/ - 105 hands in the rules engine - 2024 → 2026 development and maintenance - Android + web published app and playable demo - 115.5 → 54.5 MB the web demo on mobile ## What Daker Online is, and who built it Daker Online is a social card game for Android, built by OverFuture in Zaragoza, Spain, with Unity. It is the digital version of Daker Poker, a tabletop game with its own deck inspired by poker dice ([the game's official site](https://dakeronline.com/)). Its deck changes the usual rules. Every card carries two values, and you can only use one of them. That opens up more hands, and the same cards can be read in several ways. The game itself was its creator's idea. Our job was to turn it into a product: put the rules into code, build the online tables and ship it. - **Genre:** Social card game - **Platforms:** Android and web demo - **Engine:** Unity 6 and C# - **Multiplayer:** Photon PUN 2, up to 6 per table - **Services:** Laravel and Firebase - **Languages:** Spanish and English - **Development:** OverFuture, Zaragoza - **Rating:** PEGI 18, simulated gambling ## From a physical deck to an online table - Before the app ### A tabletop game Daker already existed as physical cards, with a ranked table of 105 hands. That table is the foundation of the whole build. - **January 2024.** ### The mobile launch The first mobile version comes out. You play against a dealer controlled by the game. We wrote about it in [the mobile launch post (in Spanish)](https://overfuture.dev/blog/daker-juego-de-cartas/). - **August 2024.** ### Online multiplayer We add online tables and rebuild the interface from scratch, with a leaderboard and customisation. More in [the multiplayer post (in Spanish)](https://overfuture.dev/blog/daker-poker-juego-de-cartas/). - About a year after launch ### 5 with Discard A second, faster mode arrives: five cards, up to four players and a discard of up to two cards. - **October 2026.** ### A demo in the browser We bring the game to WebGL so people can try it without installing anything. It is still maintained: the latest Google Play release is from March 2026. ## A hand evaluator for cards worth two values In classic poker, each card has one value. In Daker, six cards with two values each can be read in many ways. The game has to find the best reading on every turn, for every player. We solved it with data instead of writing a condition for every case. The 105-hand table is loaded into the game exactly as it is. With the six cards on show, the engine generates 1,736 combinations and removes the duplicates. Then it walks the table from top to bottom and keeps the first match. That has a practical advantage for a game with its own rules. If the ranking of a hand changes, you edit one row and the logic stays untouched. The table the game uses, from highest to lowest. [See the full table](https://overfuture.dev/en/products/daker-online//productos/daker-online/img/daker-online-tabla-105-jugadas-1200.webp) ## A table that survives losing whoever runs it Photon connects the players, but the game doesn't run on a server of our own. It is run by one of the players' phones, the Master Client. It deals, passes the turns, plays for the bots and closes each hand. That design has an obvious weak spot: a phone can lose signal mid-hand. So every device keeps the last table state it received. If the host drops out, another player takes over, restores that table and replays the last move with the timers reset. Anyone who disconnects has 25 seconds to get back to their seat, and the game retries every second. If the table stops sending signals, a watchdog warns the player and takes them out of the room ten seconds later. Nobody is left staring at a dead game. ## Bots that fill the table and pots that always add up ### There is always someone to play with An online table needs people, and at certain times of day there aren't any. Up to five bots take the empty seats and give them up when a person joins. They take between two and five seconds to decide, so the game keeps its pace. They play by the hand table, with an element of chance thrown in. - Up to 5 bots per table - 2–5 s per decision - No bots in games between friends ### All-ins never leave the chips out of balance A player who goes all-in with fewer chips can't win everything on the table. The game creates one pot per betting level and knows who is eligible for each one. We checked the maths against public pot calculators. A real example from the tests: chips bet per seat Seat A 25 Seat B 25 Seat C 356 Seat D 356 Main pot of 100, for all four seats Side pot of 662, for C and D only ## Bringing the game to the browser without a huge download In October 2026 we released a demo you can play in the browser. The first build weighed 115.5 MB compressed and used 495 MB of memory, far too much for a demo. We brought the size down in measured steps, one at a time. First we compiled for size and removed unused demos and folders. Then we capped the size of 130 textures and stripped exception stack traces. The game looks exactly the same. On mobile we went further, with a second build. The page checks whether the browser supports ASTC textures and picks the build that suits it. The demo never touches real data either: a single switch cuts all its connections to production. [Unity game development at OverFuture](https://overfuture.dev/en/unity-development/) ### Weighing the build Compressed MB at each step - First build (gzip) 115.5 - Compile for size, with LTO 110.0 - Unused demos and folders removed 102.3 - 130 textures capped 89.1 - Exceptions without stack traces 86.3 - Final on desktop (DXT) 85.4 - Final on mobile (ASTC) 54.5 - **Memory, first build:** 495 MB - **Desktop:** 320 MB - **Mobile:** 166 MB Measured on every build. The intermediate steps were linked without LTO to speed up testing. Does your game need a lighter web demo? [Let's talk](#fc-caja) ## How we work on a game like this ### Rules before graphics We start with the hand table and the engine, which is what makes the game unique. Animations come later and never decide anything. [Try it on the engine test bench](#banco) ### A table that works offline Multiplayer mode also runs offline, with bots. That way we test whole hands without needing anyone else online. [Watch the table simulation](#sala) ### Force what almost never happens We left test switches in place to trigger situations that hardly ever come up in play, like the five-aces jackpot. [See the five aces](#cartas-arriba) ### Ship and keep going A connected game doesn't end at launch. We keep it up to date with Android and Unity, and today the project runs on Unity 6. [See the project history](#historia) ## What Daker Online is built with ### Unity 6 and C# The whole game: 40 scripts of our own and 21,988 lines of code. ### Photon PUN 2 Rooms, messages between players and reconnection. ### Laravel Accounts and player data on dakeronline.com. ### Firebase Cloud Messaging Push notifications on the phone. ### Anti-Cheat Toolkit Protects what the game stores on the device. ### WebGL A browser demo, with DXT and ASTC builds.
