How to use this in play
Only 2 digit sets sum to 22 across 3 cells, which makes this a near-locked cage. Each combination shares most of its digits with the others — see the locked-digits row above for the digits forced into the cage regardless of which combination is in play.
Locked digits: 9. Whichever combination is in play, this digit sit somewhere inside the cage — meaning the cage's shared row, column, and box can't have it anywhere outside the cage.
