For those who like a chain after basics ... plus difficult non-chain step(s). (M-Ring isn't it!)

Code:
 +-----------------------+
 | 8 . 2 | . . . | 1 4 . |
 | . 1 . | . . . | . 3 . |
 | 9 . 3 | 1 . 6 | . . 8 |
 |-------+-------+-------|
 | . . 8 | 2 . . | . . 1 |
 | . . . | . . . | . 8 . |
 | . . 4 | . . 7 | . . . |
 |-------+-------+-------|
 | 4 . . | . . . | 9 6 . |
 | 6 8 . | . 5 . | 4 2 . |
 | . . 7 | 4 . . | . . 3 |
 +-----------------------+

So a bit contrarian for me, two steps - nice chain and then a monster colour wrap....

Quote:
(9=6)r1c9-r1c2=r2c3-(6=5)r5c3-(5=3)r5c6-(3=9)r4c5; r1c5<>9
Colour wrap(6); r1c9,r2c3,r2c7,r4c2,r5c3,r6c9<>6
