Also added "definitely red" and "definitely blue" markers. **2023-05-26** Added the "unshaded tile" mark, a suggestion by @Yuyuki. **2023-05-30** Improved the loop colouring algorithm, after suggestions of @Yuyuki, @TheGreatEscaper and @Menderbug. **2023-06-12** Further changes to the loop colouring, after suggestions of @Yuyuki and @Menderbug. **2023-06-17** Thanks to @TwoHoleStraw for suggesting the UI buttons remain pressed once selected! **2023-09-08** Like in RGB Loop, shaded cells now retain border so that the underlying colour can be seen - thanks @Yuyuki, @MonokuroGreen and @Menderbug for feedback! **2023-09-11** Added links to the two variants (thanks @Yuyuki) **2023-11-13** Patched a dragging bug reported by @AlbeyAmakiir - thank you! **2023-11-27** Fixed a non-uniqueness found by @Random8 (as well as a minor regression) - thank you! **2023-12-19** :::puzzletters @PinkHoodie sent a classic RB Loop puzzle to celebrate PuzzleSquare Advent Calendar 2023 **2023-12-20** Variant ´´no-shade´´ added (replaces usage of full variant, which was already included by default in the base rules of RB Loop) **2024-01-01** @PinkHoodie made a ´´hasu-no-mura´´ mashup, combined with the recommended ´´full-optional´´ variant. **2024-03-02** Two additional puzzles by @PinkHoodie: one classic and one using the ´´loop-to-path´´ variant; style upgrade to line-of-sight **2024-06-10** Recent regression found by @yuyuki was reverted (cause: consolidation of colorisation and multi-line conflict template as one) **2024-06-29** @PinkHoodie crafted a puzzle using variant ´´arrow-yajilin-solve´´! **2024-09-30** Collision behaviour improved (circle aux marks vs lines) after feedback from @Yuyuki, who also reported a colorisation regression, now fixed. Thank you! **2024-11-07** Minor improvement to the [RB loop] colouring algorithm. **2024-11-26** Further improvement to the [RB loop] colouring algorithm, which now also propagates when the loop is closed, after @PinkHoodie sent some good test cases. **2024-11-26** The aux loop colour marks were replaced by a letter; a bug reported by @PinkHoodie with those in the´´rb´´ variant was corrected.
