Something we've made a regular thing over in the CTC discord is having a biannual swap week (every Feb and Aug) between the Genuinely Approachable puzzle teams. Normally I'm on the GAPP team, and I have many posts here on the site about it, GAS on the other hand does (mostly) variant Sudoku, something I find a lot more intensive to make! That said I do always have fun with these, here are my two main puzzles from this years swaps, and a couple bonuses too (that are slightly tougher). For all puzzles: Each row, column, and 3x3 box must contain the digits 1 through 9 February - 159 Sudoku Each digit in column 1 indicates which column the 1 appears in its respective row, each digit in column 5 indicates where 5 appears in the row, and each digit in column 9 indicates the 9 in the row Solve on F-Puzzles
August - Kropki Pairs Sudoku Cells separated by a white dot must be consecutive, and cells separated by a black dot must have a 1:2 ratio Solve on F-Puzzles
