The 6x6 puzzle can be played here: https://app.crackingthecryptic.com/sudoku/Q4htQQBFJP and the rules are below
1-6 must be placed in each row, column and region, but the regions (six cells, orthogonally connected) need to be determined. A digit in a circle indicates the number of borders between regions it sees in its row and column. Note that the edge of the grid does not count toward this total. Not all circles are necessarily shown.
