9/04/12 Advancing on Unsolvable #40 Illustrates ALS stuck numbers
9/11/12 Unsolvable 40 Beats ALS Unsuccessful ALS enumeration
9/18/12 LPO vs Unsovable 40 Color panels and single conflict table
9/25/12 Unsolvable 40 Solved? Reduced, colored conflict tables are reluctantly solved by trial
10/16/12 Scrounging Pattern Sets in LPO LPO conflict analysis on Unsolvable 40
10/23/12 The Pattern Slink A new form of conflict table. The pattern slink does a color wrap,
10/30/12 Unsolvable 40 Logically Solved and delivers solution without trial.
The Golden Nugget
10/19/13 Experimenting with The Basic results and LPO orphans search fails. Golden Nugget Pattern slicing trial fails with no progress, but clears fog
12/10/13 Nugget’s Exocet Exocet defines four trials with cut and paste nice loops.
12/17/13 Packing for the GN Nice loop removals and pink olive slices for the Exocet Assault assault trials
12/24/13 Three Golden Nugget Traces of first three failing trials. Exocet Trials
12/31/13 Human Solves Golden Nugget The final Exocet trial.
2/23/14 Steve’s Opening Volley Basic solving, Kurzhal’s opening volley
3/4/14 Snake Attacks Easter Monster Sudoku Snake interprets opening volley as a naked double loop
3/18/14 Advancing Colors On The EM Two naked triples, mini corner clusters, patterns for blue to yellow merge.
3/25/14 Core Patterns in the EM Blue to purple, red to maroon and red to grey patterns
4/01/14 Coloring Cluster Trials on the EM Red to grey trial proves red merges into maroon. Blue to yellow commits EM to orange.
4/08/14 An Easter Monster Alibi Holds Up Orange proves too much, and blue to yellow merge fails
4/15/14 The Easter Monster is Convicted Freeform patterns are trimmed in blue to purple trials. Blue and red cluster armies win.
Hanson and Maranz’ Easter Monster
4/22/14 The Hanson and Marans EM The HM slink loop strategy. Sysudoku double nasty loops
4/29/14 The HMEM SK Loop Removals from the four HMslink loops. The equivalent SK loop
5/06/14 Building a HMEM Blue/Green Cluster Questions the loop linking HM strategy, but proves the slink between 3, 7 loops.
5/13/14 A Second Cluster for the HMEM Establishes the link between 4, 6 loops, as claimed by HM.
5/20/14 A Colorful Trial on the HMEM Intense pattern analysis reaches a wrap on one cluster. HM offers nothing similar.
5/27/14 Sysudoku Solves the HM Easter Monster Swordfish and a grouped forcing chains expand blue/green. Then a forcing chain and SdC wrap green. An HM plan, but a sysudokie solution.
6/16/15 The Fata Morgana Exocet identifies the exocet and reviews the Sysudoku interpretation of it as a trial generator. Reveals the trial structures as nice loops constructed from interchangeable ANL, and displays two of them.
6/23/15 Trial 13 of Fata Morgana checkpoints the third trial nice loop for readers and completes the first trial.
