Frequently Asked Questions
Quick answers to common questions about gameplay rules, math evaluation, daily puzzles, and technical features.
1. Rules & Gameplay
What is 67DLE?
67DLE is a free daily mathematical puzzle where you use only the digits 6 and 7 along with the four basic arithmetic operators (+, -, ×, /) to match a target value. It tests mental arithmetic, logic, and operational hierarchy.
How does order of operations (PEMDAS/BODMAS) work?
Calculations in 67DLE adhere to standard mathematics: multiplication and division take precedence and are solved first from left to right, followed by addition and subtraction. For instance, 6 + 7 × 6 is evaluated as 6 + 42 = 48.
Can I combine digits into multi-digit numbers?
Yes! In Equation 67, you are free to enter multi-digit combinations using 6 and 7, such as 66, 67, 76, and 77. This allows you to reach larger targets efficiently.
How does equation feedback work?
When your equation successfully evaluates to the target number, all tiles light up in green and trigger the victory celebration! If your equation results in a different value, the tiles shake in red and your attempt is logged in the Attempt History list showing your exact calculated result so you can adjust your next formula.
2. Game Modes & Features
What are the three game modes?
Equation 67: Deduce an equation to equal the daily or random target number.
Arrange 67: Rearrange all given tiles in your keyboard tray to form an equation that equals 67.
Crossword 67: Solve a 5×5 grid where every intersecting line calculates to 67.
What is Random Mode?
Random Mode generates endless procedural mathematical puzzles on demand. You can click the reroll button to generate a new target anytime to practice without waiting for the daily reset.
3. Daily Resets & Archive
When does the Daily Challenge reset?
The daily puzzle resets automatically at midnight (00:00) in your local timezone every day. All players worldwide share the same challenge for each day.
Can I play previous days' puzzles?
Yes! Use the left arrow button in the header or click the date to open the Calendar Archive. You can jump back to any previous puzzle date to play or replay it.
Will playing past puzzles break my current streak?
No. Your win streaks and daily completions are recorded safely per calendar date, so exploring past games in the archive will not reset or damage your streak.
