Speedcube Timer & Scrambler
Train your solves with WCA-compliant scrambles, an instant-start timer and live session statistics for four twisty puzzles.
What is it?
A speedcube timer is the essential training tool for anyone learning or improving their Rubik's Cube solving speed. Instead of fumbling with a phone stopwatch, a dedicated timer gives you sub-millisecond precision and an experience that mirrors a real WCA competition: hold the spacebar (or tap the screen) to arm the timer, release to start, and tap again the moment you place the cube down after solving. This free online timer supports four puzzles in one place: the classic 3×3 Rubik's Cube, the Skewb, the Pyraminx and the Ivy Cube. For each puzzle the tool generates random scrambles following WCA notation conventions, so your practice mirrors real competition conditions. The session panel tracks your last twelve times and automatically calculates your best single, session mean, average of 5 (ao5) and average of 12 (ao12) — the same statistics judges use at official tournaments. The Solve Guide tab provides a step-by-step beginner's method for each puzzle, so you always have a quick reference when you get stuck mid-solve.
How to use it
- Select the puzzle from the top tabs: 3×3, Skewb, Pyraminx or Ivy Cube.
- Read the scramble shown at the top and apply it to your physical cube.
- Hold the spacebar (or long-press on mobile) until the display turns green — the timer is armed.
- Release the spacebar to start the timer the moment you begin solving.
- Press the spacebar again (or tap the screen) the instant you place the solved cube down.
- Your time is logged automatically. The session panel updates ao5, ao12 and best single in real time.
- To delete a time, click the × next to it in the session list.
- Switch to the Solve Guide tab for step-by-step instructions for the selected puzzle.
Why use this tool
Speedcubing is one of the fastest-growing competitive hobbies worldwide, and consistent practice is the single biggest factor separating beginners from sub-30 solvers. A purpose-built timer removes every friction point: you do not unlock your phone, you do not click start and stop awkwardly, and you get your stats updated the moment you finish. The WCA scrambles generated by this tool are random enough to train your recognition for any starting position. Beginners benefit because they cannot memorize patterns — every solve is a fresh challenge. Intermediate solvers benefit because their ao12 and ao100 trends show exactly where they are improving and whether their cross, F2L, OLL or PLL is the bottleneck. The four puzzles share the same interface, so you can rotate between your mains and backup puzzles without switching tabs or apps. The session history is kept in memory for the duration of your visit, which means no data is ever stored on a server or tied to an account. Bookmark the page, open it on any device, and your timer is ready in seconds.
Frequently asked questions
Are the scrambles WCA-compliant?
Yes. The 3×3 scrambles are 20 moves long and follow standard notation (R, L, U, D, F, B with ' for inverse and 2 for double). Skewb uses R, L, U, B with modifiers. Pyraminx and Ivy Cube use their respective WCA notations.
How is ao5 calculated?
Average of 5 (ao5) takes your last 5 times, removes the best and worst, then averages the remaining three. ao12 works the same way over 12 times. This is the standard WCA calculation.
Can I use this on mobile?
Yes. On mobile you tap and hold anywhere on the timer display to arm it, then release to start and tap to stop. The touch controls mirror the spacebar behaviour on desktop.
Does the timer save my times between sessions?
Times are kept in memory for the current visit only and reset when you close or refresh the tab. For long-term tracking, note your ao12 or take a screenshot before closing.
What is the Ivy Cube?
The Ivy Cube is a face-turning octahedron-shaped puzzle with four corner pieces and four edge pieces. It is one of the easiest twisty puzzles to learn — most solvers crack it in under 10 seconds after a few hours of practice.
What is the difference between Skewb and 3×3?
The Skewb turns on its corners rather than its faces. This means all eight corners move with each turn, making pattern recognition quite different from a standard Rubik's Cube. It is an official WCA event with world records under 1 second.
