Practice spotting sets
Once you know the rule, getting faster is a matter of practice. Threezy gives you an endless untimed board to train on, short timed sprints to measure yourself, and real numbers from other players so you know where you stand. Free, in the browser, no account.
Three ways to practice
- Flow (untimed). An endless board with no clock. Each set you find is replaced by three new cards. Use it to build the habit of scanning calmly; it rewards long unbroken chains rather than raw speed.
- 2-minute sprint. How many sets can you find before the clock runs out? This is the benchmark mode, and the one the table below is based on.
- Race 10. Find ten sets as fast as you can on a random board. Short enough to repeat a dozen times in a coffee break.
Where do you stand?
Scores in the 2-minute mode, from Threezy players with at least ten games (each player's typical game, not their best).
The highest single game on record is 124 sets in two minutes, just under one second per set.
What fast players do differently
- Start from a pair, not a triple. Any two cards decide exactly what the third card must be. Pick two cards, name the missing card in your head, and look for it. That is one check per pair instead of guessing at triples.
- Hunt the easy sets first. Sets where one feature is all the same (three circles, three red cards) are the quickest to see. Scan for a repeated feature before trying all-different sets.
- Don't re-read the whole board after every set. Only three cards changed. Check the new cards against what you already know.
- Watch the fill. It is the feature beginners miss most: solid, striped and empty are easy to blur together when you hurry.
- Accept the slow board. Some deals hold only one set. Fast players lose their time on those boards, not on the easy ones, so staying calm there matters more than tapping faster.
Track your progress
Your profile keeps your rating, your score and your seconds per set over time, plus personal records for every mode and your fastest chains. The rating is one number across all timed modes, so a sprint and a 2-minute game count toward the same ladder, from Rookie up to Legend.
Questions
Is there an untimed practice mode?
Yes. Flow (the infinity pill) is endless and has no clock. Find sets at your own pace; it tracks your longest unbroken chain and your fastest chains of 3, 5, 10 and 25 sets, so you can see yourself improve without the pressure of a countdown.
How long does it take to get good?
The typical first game finds about 10 sets; regular players settle between 15 and 20. The early jump comes from the rule becoming automatic. After that, progress is slower and comes from scanning habits rather than from knowing the rule better.
Do hints hurt my rating?
A hint shows one valid set and costs 5 seconds of game time, so it lowers the score of that game. In Flow there is no clock, so hints there are free practice.
Is this the same as practicing for the physical card game?
The rule is the same idea: every feature all the same or all different. Threezy uses three features (shape, colour, fill) instead of four, which makes the board faster to read. The 81-card mode adds the fourth feature, number, if you want the full version.
