${DynamicText("About this genre (loading...)")} The name [Tumbleweed Loop] was chosen here to avoid confusion with the older genre [Tumbleweed], a change that @Seren did not object to. This implementation contains circles outside tile centres, namely at vertices and edge midpoints, a suggestion by @Seren, who explored the former. The rule panels were adapted from @Seren's original example puzzle, transcribed below. ## [tumbleweed-loop] Puzzles ### @Seren W=4x4x1&L=x0b1b1w5x5b1x1x1&SSE=37ICOAKACBMKJG&G=tumbleweed-loop&A=Seren&D=2025-01-23&N=1&T=Example W=4x4x4&L=b0b1b5b1b2b2b1b3b1b3b1b7b1b2b3b1b1b1&G=tumbleweed-loop&A=Seren&D=2025-01-24&F=3&N=2&T=Moat ### @PinkHoodie W=3x3x3&L=w2b3b1b3x3w2b2x2&L-E=b13&L-V=w9w22&SSE=15HABCAHKFGJIOCBNHJ&G=tumbleweed-loop&A=PinkHoodie&D=2025-01-24&F=2&T=Tubled W=16x6x1&L=b3w1w1b3b1b1b3w1b1w1w1b1w1b2w2b2b1w1w1w2b4w1b2w1w3w1b1b2b3w1b2w1w1w1b2w2b1b1b1b1w1b1w1b2w3w2w2w2b1b1w3b1w1w1w1b1b1w2w1b1b1w2&L-E=b85b11b33b32w19b6w7b28b28w4w2b5w5&L-V=b6b15w23b15w35b21w8w3w39w3w50&SSE=169FGMKFCOCFHKHMHABCBCAHGKMABFCBCIOCICGFOABIOCFKFGMBAKJHGIBCFOCANCFGFONAMBFIFJIGAHGHMHKHMKABMHBCAHK&G=tumbleweed-loop&A=PinkHoodie&D=2025-01-25&F=3&T=16x6_1 ## Acknowledgements and Changes **2025-01-23** Thanks to @Seren for the detailed suggestions for a possible implementation, including the auxiliary tile-centered loop (here using sketch lines) and off-centre circles (vertex and edge midpoint)! **2025-01-24** @Seren sent a new [Tumbleweed Loop] puzzle for rollout - thank you! **2025-01-24** Thanks to @PinkHoodie for sending a [Tumbleweed Loop] puzzle for rollout, using absent cells and clues at various positions relative to the tile centre! **2025-01-26** An impressive 16x6x1 [tumbleweed-loop] (classic) puzzle was sent by @PinkHoodie for rollout!
