Nice one, thanks. Had to remain viligant at all times lest I fall into the obvious trap.

Very nice. Easy-peasy, once you understand the implications of the ruleset. Thanks, mathpesto.

Very fun puzzle! One has to throw away part of the typical sudoku mindsets in order to avoid making some stupid mistakes (which I made multiple times :p). It flows quite smoothly once I got used to the rule set and start asking the right questions. Thank you!

@twobear: Thank you! Even when initially setting it, I kept making those same mistakes. It was a nice challenge that forced me to disregard certain strategies that are so ingrained for me, so props to zetamath for posing this Fiveless Challenge!

Removed one cage and moved another cage (doesn't affect solution)
