The CILOPSY tetrahex labelling, as in SLICY and Joseph Howard's CYCLOPS puzzle is used.

The following labelling scheme for pentahexes is used:

This differs from Abaroth's prior scheme, in that 7 pentahexes were relabelled, the remaining 15 pentahexes coincide. The reason for change was so their assigned letters are easier to recognise and to keep in working memory while solving a puzzle (if not memorise for the long-term), thus hopefully smoothening the experience and reducing mistakes. The new assignment was tested by about a dozen puzzlers, using a unlabelled test picture (blind perception test) and/or via active feedback on the labelling scheme as such. It was subsequently refined, holistically, leading to adjustments to individual labels as well as their presentation (rotation, mirroring, superimposed letter shapes).

TBA.

To make a "polyminous (borders)" puzzle, simply apply global variant edge-given.

Thanks to everyone else who tested and/or provided feedback about the labelling: Hazelstorm, Cjk, Anurag Sahay, Seren, Nabokos, Beekie, Botaku, Yakaki, Emmie, Skyeislime, and others. 2024-10-04 Thanks to Anurag Sahay for sending a rollout Polyominous puzzle! 2024-10-04 Thanks to PinkHoodie for sending a rollout hex Polyominous puzzle, and noticing that the edge-given variant should be part of the recommendations (added). 2024-10-05 A polyominous borders (as edge-given) and a third rollout puzzle were sent by PinkHoodie, both on the hex grid. Thank you! 2024-10-06 A polyominous borders (as edge-given) was sent by Anurag Sahay for rollout - thank you! 2024-10-07 The genre was promoted to global variant polyominous. 2024-11-05 A bug in the global variant polyominous, detected by PinkHoodie, was patched (letters are now unrestricted, and it is up to the setters to pick the correct ones) 2024-11-16 puzzletters PinkHoodie shared 1 Polyominous puzzle using variant edge-given! 2025-01-04 puzzletters A classic tetromino Polyominous was finally made, composed by PinkHoodie - thank you! 2025-02-02 puzzletters PinkHoodie dispatched 1 Polyominous (classic) puzzle - kiitos! 2025-02-11 Encoding Polyominous parameter encoding and display was upgraded, so that the parameter now appears in puzzle pictures.
