The Quadro guide
Everything about Quadro in one place — the rules, how the wall scores, the strategy that actually moves the number, and what each of the six AI opponents does.
Quadro is a two-player tile-drafting game played against an AI opponent, in your browser, for free. Every day it deals one puzzle that is identical for every player, and ranks everyone by how far they beat their opponent by.
If you have never played a tile-drafting game before, start with Learn to play — it is a scripted round on the real board and takes about two minutes. The pages below are the written version, for when you want to look something up.
Start here
- The rules — the whole game in one page: the two clicks of a turn, pattern lines, the floor line, and how a round ends.
- How scoring works — why placing next to your own tiles is worth several times as much as placing in empty space, and what the end-game bonuses are worth.
- Strategy — the handful of decisions that actually separate a 20-point game from a 60-point one.
- The six opponents — what Easy through Extreme actually do, and which board is worth chasing.
- Frequently asked questions — sign-in, offline play, the daily reset, and how the board is ranked.
The two ways to play
Quadro has one competitive mode and one sandbox.
Daily Challenge deals one puzzle per day from a shared seed, so every player in the world faces the same five factories in the same order. You pick which of the six opponents to face, play the game out, and your score margin — your final score minus the opponent's — goes on that opponent's board. Each opponent has its own board, and you get one recorded attempt per opponent per day. The puzzle rolls over at midnight New York time.
Practice is the same game with none of the pressure: any opponent, any deal, untimed, and nothing is recorded anywhere. It also runs fully offline once the page has loaded, because the AI runs in your browser rather than on a server.
Is this Azul?
No. Quadro is an original implementation of the tile-drafting genre that the board game Azul popularised, and it is not affiliated with or endorsed by that game's publisher. The family resemblance is real — factories, pattern lines, a scoring wall, a floor-line penalty — but the numbers, the opponents and the daily format are ours. If you came here looking for a free daily tile-drafting puzzle to play in a browser, you are in the right place.
