COALL

COALL method Information about the method Proposer(s): Proposed: Alt Names: ELLCP, CPELL, KLL, WW, Anti-ZBLL Variants: No. Steps: 4 No. Algs: 63 (unique) + 21 (PLL) = 84 (total) Avg Moves: est. 35-50 Purpose(s): Speedsolving

COALL (Corner Orientation And Last Layer) is an experimental 3x3 method, a ZB variant that orients the last-layer corners when inserting the last F2L pair (COLS). It has no known user. Orienting the corners first, rather than the edges like in normal ZB, has the advantage of requiring less algorithms (111 total compared to ZB's 300).

To solve using COALL, solve the cross and three F2L slots using any method. Next, make the last F2L pair while using COLS to insert it and orient the last-layer corners. Finally, finishsolve using XLL.

Pros

• Much fewer algorithms than ZB and perhaps as fast
• Reasonable recognition

Cons

• Relatively large number of cases (111, including 21 PLL)
• Has some bad algorithms
• An extra look during Winter Variation/Too many algorithms with COLS
