About this puzzle

Easy here means between 36 and 45 of the 81 numbers are already printed, and that the grid can be finished with single candidates alone. It was graded by being solved by a program that knows the techniques, one at a time, and rejected if it ever had to guess — so there is exactly one answer, and it is on the second page.

This particular grid starts with 42 of the 81 numbers already printed, and the hardest technique it asks for is: Hidden single.
