Post subject: | some stats on the "Calcudoku Advanced, volume II" book |
I thought it could be about time for a volume III, and wanted to run some stats on the submitted puzzles of volume II. Number of submissions by month: Oct 2014: 260 (the first on Oct. 16) Nov 2014: 415 Dec 2014: 383 Jan 2015: 445 Feb 2015: 217 Mar 2015: 282 Apr 2015: 43 About 2% of submissions have comments about the puzzle (mostly about how easy/difficult the puzzle was). The easiest puzzles: a2s1, a2s2, a2s3 (two 8x8 and one 9x9 single operator puzzle), a2n1 (the first 6x6 no-op), a2t1, a2t11 (a 6x6 and a 4x4 twin) (so no surprises there ) (all submitted 18-22 times so far). The hardest ones: a2x11 (the 17x17), a2v2 (a 5-star "patterned" 10x10) (both submitted 8 times so far) submitted 9 times: a2x10 (the last 15x15), a2g2 (a 6x6 using {-1,....,4} (!)), a2z17 (a 9x9 from zero), a2m14 (8x8 with mod), a2s16 (9x9 single-op), a2n10 (10x10 no-op), a2n7 (9x9 no-op), a2e14 (10x10 with exponentiation and zero), a2g5 (11x11 using {-5, ..., 5} The drop in the number of submissions does suggest it's time for a new volume (that or I'm not promoting the book enough ) Patrick |
