A Game of 5 by Glow-Worm

This was an entertaining and elegantly constructed addition to Glow-worm's series of "game" puzzles, this time based on the game of "Kiss in the Ring", which appeared in the central column. The solver was given quite a bit of help from the outset, with the special clues being flagged as such. Often it's left to the solver to determine which clues are of special types. In any case those clues had the rather novel feature of needing a name inserted into them before they could be solved. As an additional hurdle, their definition elements were misplaced. Given the information revealed in the preamble the hidden names were not hard to find in the grid, particularly Katie and Peter crossing right in the centre. Only the perimeter quotation, from Shakespeare (Twelfth Night), took any real effort to uncover, given the vagaries of the ODQ index: Then kiss me, sweet and twenty/Youth's a stuff will not endure.
