Code: Select all: *-----------------------------------------------* | 1 89 23 | 36-2 368 *29 | 7 4 5 | | 4 89 23 | 7 358-1 5-129 | 129 129 6 | | 6 5 7 |*124 *14 *1249 | 3 8 129 | |----------+--------------------+---------------| | 8 23 1 | 5 9 6 | 4 7 23 | | 7 34 6 | 8 2 14 | 5 139 139 | | 5 24 9 | 14 7 3 | 6 12 8 | |----------+--------------------+---------------| | 23 1 5 | 2349 34 7 | 8 6 239 | | 23 6 4 | 1239 135 8 | 129 12359 7 | | 9 7 8 | 1236 1356 125 | 12 1235 4 | *-----------------------------------------------*

The next step would be a naked quad (1249) in the 4 cells marked * in Box 2. It solves r2c6 = 5 but not the whole puzzle.
