Is it possible that one could make the puzzles with a set of 9 pictures instead. Thanks.

This algorithm can replace the techniques included in the fish strategies from the following chapters. Below are presented the few examples from the next 5 chapters. The other examples can be solve in the same way. For each candidate-digit will be determined the cells in which the candidate can take values. In this way we’ll obtain nine 9x9 matrix m1, m2, …m9 with n1, n2, ….n9 candidates with k1, k2, ….k9 lines, columns, blocks. The next step consist in calculus of numbers of possible cases N_i=C_(n_i)^(k_i ), i=1:9. For each case will be verify the accomplishing of bases conditions. If these conditions are not accomplished, from the unsolved cells, the candidate or candidates of those presence can introduce errors will be eliminated. Basic Fish JellyFish m7 – n7 = 29, k7=8 r2c2, r7c8, r8c8, r9c9, r7c9, r8c9 ><7 m9 - n9 =17 , k9= r2c2, r7c2, r1c9 ><9 Finned/Sashimi Fish 2.1 Finned/Sashimi Swordfish m2 - n2 =26, k2=7 r6c2><2 => r6c2=1 Solve r3c4><2 => r3c4=1 Solve r4c5><2 => r6c4=2 Solve r5c5 ><2 Complex Fish Siamese Fish m8, n8 =23 k8=6 r5c1 ><8 => r5c1=1 Solve r9c2><8 => r9c2=9 Solve Single Digit Pattern 4.1 Skyscrapen m4, n4 =13 k4=5 r2c1><4 => r2c1=6 Solve r1c4><4 => r1c4=6 Solve r5c5><4 => r5c6=6 Solve r2c6><4 => r1c6=6 Solve m6 n6 = 21 k6=6 r5c5><6 5.1 X Chain m7 n7=16 k7=5 r4c2><7 =>r4c2=4 Solve In order to keep the computing time in range of few seconds, n must be lower than 30. The program can solve all the examples from the “Fish strategies”.

There is room for improvement. One fundamental rule is to verify if the puzzle has multiple solution, It is not a Sudoku is it has multiple solution.

Great program with levels from very easy to insanely difficult. Unique feature is the 'Extended Print' I use this to print 2 puzzles per page. 5 pages at a time, then turn over the stack and print 2 per page on the other side. Select 'Extended Print' from file menu. select 2 per page in layout, then fill in each section eg number puzzles '2'; Difficulty 'Hard' then use slider on right to go to next section (5 sections in all) In 2 or 3 minutes with laser printer and I have 20 puzzles to take with me.
