In addition, the genre [Alcazar] shares much of the same logic.

### ´´unequal-lengths´´

This variant can be seen to stem both from **simple loop** or of from [Unequal Length Mazes]. It was devised by @ft029:

#### @ft029
W=19&H=11&L=x0x1x3x1x7x5x5x2x6x1x59x1x1x1x1x1x11x1x2x12x19x1x3x10x2x2x9x8x7x1x4x13x1x25x1x1x5x1&G=simple-loop&V=unequal-length&F=4&A=ft029&D=14/02/2022

#### @apiad

##### Minimum-clue page.title

All other minimum clue page.title puzzles with dimensions 9x9 to 11x11 were found by @Apiad via a computer search.

These puzzles do not necessarily have a clean logic path and were included for completeness.

## Changes

**2023-02-15** Created the Unequal Length Loop page, with puzzles from @ft029 and @apiad
**2023-09-08** Added the ´´crossing´´ variant, and gathered all other simple loop variants in this page
**2023-09-12** The grid is now checkered by default, lines are multi-coloured, and shading aux marks can be kept alongside lines
**2023-09-18** Added the variant ´´directions´´ by @Millay
**2023-09-22** Added the variants ´´hex´´ by @scor and *kiki* by @Menderbug
**2023-09-23** Merged the Unequal Length Loop page into Simple Loop
**2023-11-09** Opposing directional arrows erase each other in the directions variant - thanks @Rubrica!
**2023-11-14** Directional arrows now work within the hex variant, as first tried by @PinkHoodie.
**2023-11-16** The ´´vertigo´´ variant by @Endagorion was added!
**2024-20-03** A ´´hex´´ puzzle by @PinkHoodie, making use of the new hex checkerboard pattern, was listed - thank you.
**2024-05-03** @PinkHoodie sent 1 puzzle using variant ´´crossing,no-shortest´´!
**2024-05-24** @PinkHoodie sent 6 classics - thank you!
**2024-06-03** @PinkHoodie sent 2 further classics - thank you!
**2024-07-06** @PinkHoodie sent 1 classic this week, and found a day regression related to the ´´short´´/´´shortest´´ variants, now fixed (cause: registration missing after switching from implicit to explicit) Thank you!
**2024-07-12** @PinkHoodie sent 4 classics - thank you!
