What is Threezy?
Threezy displays nine cards and asks you to spot three that form a valid triplet. Each card has three properties: shape, color, and shading. A triplet is valid when, for each property, the three cards are either all identical or all different. The site guarantees at least one valid triplet always exists on the board.
How to play Threezy
- Choose a mode from the tab bar: race to ten triplets, a two-minute timed game, or endless mode.
- Tap three cards that follow the rule for each of the three properties. For every property, the selected cards must show either three identical values or three different values.
- Use the keyboard to select cards faster. Its nine-key layout matches the card layout.
- Keep selecting triplets until you reach the mode’s goal. In timed modes, the hint button reveals one triplet and costs five seconds.
- Open the help panel to switch to a color-blind-friendly palette if colors are difficult to distinguish.
The feedback system shows why a selection was wrong.
Threezy identifies the property your selection violates instead of simply marking it wrong. When a triplet fails, a message appears below the board: “colour: need 3 the same or 3 different.” The triplet counter stays unchanged, while the stopwatch keeps running. This feedback lets you learn the rule through practice instead of guessing.
Game modes and objectives
In Race to ten triplets, find ten triplets as quickly as possible. The counter shows your progress out of ten, and the stopwatch records tenths of a second. You can try to beat your personal best.
Two minutes is a timed challenge on the daily shared board. Find as many triplets as possible in 120 seconds, then compare and share your result.
Flow is the endless mode for relaxed play. Build chains and sprints without a time limit. A table records your longest chain.
A fourth tab appears in the mode bar under the name Race 10.
Strategy and practical tips
If you cannot find a triplet, try a different property. The board always has at least one valid set. When nothing stands out, switch from color to shape or shading.
In timed modes, consider whether the hint is worth five seconds. That may be less time than you have already spent staring at the same nine cards.
When speed matters, use the keyboard. The nine-key block on the left or the numeric keypad matches the cards’ positions and avoids mouse travel.
If color discrimination slows you down, choose a custom palette. The help panel includes presets for red-green and blue-yellow color blindness, as well as a fully customizable option.
The board cannot run out of valid triplets; the site says that at least one is always available. You do not need an account: the FAQ says the game is free, requires no registration or installation, and runs in any recent browser. Everyone gets the same grid in the daily game, so players can compare their results.
