3x3x3 Multi-Blind - cheat sheet

2Time limit

At the limit the judge stops the attempt: cubes solved up to that moment count, time = the limit.

3Points

Points = solved - unsolved.

DNF: fewer than 0 points or only 1 solved cube. 0 points with 2+ solved counts (2/4).

Ranking: points, then shorter time, then fewer unsolved. Time in whole seconds, +2 s for each cube with a layer misaligned by more than 45°.

Result format: solved/attempted time, e.g. 3/5 40:30.

4How many cubes

• A mistake = -2 points compared with a solved cube.
• 2 cubes: one mistake = DNF. 3 cubes: one mistake = 2/3 (1 point).
• Declare as many as you solve at home in most attempts, with a few minutes to spare.
• Add one cube at a time when several attempts in a row succeed.

5Memory

• Fixed images for letter pairs (approx. 10 per cube).
• Memory palace: 2 images per locus, approx. 5 loci per cube.
• Each cube on its own stretch of the route: edges first, then corners, parity as a separate image.
• Review earlier cubes every one or two cubes, the whole route before the blindfold.
• 2-3 routes in rotation.

6The attempt

1. Start the timer, covers off.
2. Each cube: white on top, green in front, tracing, images on the route, put it down in the same orientation.
3. Reviews, the whole route, blindfold.
4. Cubes one by one; after each, check the layers with your fingers and set it aside.
5. Forgotten cube: move on, come back at the end.
6. Release the cube, stop.

7After the attempt

For each unsolved cube write down the cause: memory, tracing, execution or the cube itself - and practise the weakest part.
