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 (opens in a new tab)).
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.

Project history
Daker already existed as physical cards, with a ranked table of 105 hands. That table is the foundation of the whole build.
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) (opens in a new tab).
We add online tables and rebuild the interface from scratch, with a leaderboard and customisation. More in the multiplayer post (in Spanish) (opens in a new tab).
A second, faster mode arrives: five cards, up to four players and a discard of up to two cards.
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.
First round · The rules engine
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.

Second round · Multiplayer
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.

Third round · Table rules
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.
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
Fourth round · Unity WebGL
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.
Compressed MB at each step
Measured on every build. The intermediate steps were linked without LTO to speed up testing.
The process
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 benchMultiplayer mode also runs offline, with bots. That way we test whole hands without needing anyone else online.
Watch the table simulationWe left test switches in place to trigger situations that hardly ever come up in play, like the five-aces jackpot.
