3BLD Scrambler

Write a JavaScript boolean expression directly. The expression is evaluated for each possible cycle structure; only scrambles whose structure satisfies both the edge and corner conditions are generated.

Available variables — all integers unless noted:

• parity — 0 (even) or 1 (odd).
• breaks — number of cycle breaks, i.e. how many times the memo had to jump to a new starting piece.
• algs — alg count under Floating plain 3-cycles only. For Basic 3-style use alg; for Full Floating use algFF; for Full Floating Parity use algFFP.
• closed1 — solved pieces in-place with correct orientation (free, no alg needed).
• open1 — pieces in-place but misoriented: flipped edges or twisted corners.
• closed2 … closed5 — clean k-cycles (correct orientation) that appear as secondary cycles.
• open2 … open5 — k-cycles with at least one misoriented piece.
• cwTwist / ccwTwist — number of CW / CCW twisted-in-place corners. Corner-only; for edges, use open1 instead.

Your last 5 expressions are saved per-field. Use ↑↓ in the input to navigate history. Hitting Enter generates scrambles. The URL updates so you can bookmark or share a filter.

Examples

Floating plain 3-cycle drill

Cases where full floating saves

4-flip practice (edges)

Three or more flipped-in-place edges forces a 4-flip alg.

3-twist practice (corners)

Forces a 3-twist alg case. Two same-direction twists invoke a 3-twist; mixed CW+CCW pairs cancel into a 2-twist.

Non-buffer 2-twist (corners)

LTCT

Odd parity with a twisted-in-place corner — the canonical LTCT setup.

T2C

Easy scrambles

Heavy memo — many cycle breaks
