@CeriseTalis designed [ionic-squares] and shared it at [this page|https://plus.cerisetalis.com/penpa/ionic-squares]. Below is an interactive port. All solutions are unique. ## Original rules The original rules require 1 dot per square and 1 square per dot (1 • 1 ■) ### @CeriseTalis' [ionic-squares] W=5x5&L=d22d53&SS=15LLLUUURRRDDD7LLUURRDD&P2=1&P1=1&G=ionic-squares&A=Cerise_Talis&T=Goldfish W=7x7&L=d15d66d7d67d10&SS=6DDDRRRUUULLL8LLUURRDD16DDRRUULL4DDRRUULL2LLLLUUUURRRRDDDD&P2=1&P1=1&G=ionic-squares&A=Cerise_Talis&T=Mecha W=9x9&L=d32d6d26d65d114d38&SS=3DDDRRRUUULLL19DDDRRRUUULLL2LLUURRDD18DDDRRRUUULLL11DDDRRRUUULLL3LLLLLUUUUURRRRRDDDDD&P2=1&P1=1&G=ionic-squares&A=Cerise_Talis&T=Racketeer W=11x11&L=d35d35d11d52x15x46d53d10d32d42d36d69&SS=27LLUURRDD18LLLUUURRRDDD7DDDRRRUUULLL3LLLUUURRRDDD10LLLLDDDDRRRRUUUU10DDDRRRUUULLL15LLLLLUUUUURRRRRDDDDD10LLLUUURRRDDD13DDDLLLUUURRR5UULLDDRR&P2=1&P1=1&G=ionic-squares&A=Cerise_Talis&T=Discus W=15x10&L=d27d4d72d10d78d32d52d13x32d31x27d64d65d29&P2=1&P1=1&G=ionic-squares&A=Cerise_Talis&T=Démodé ### Community Puzzles W=10x10&L=x52d36d9d4d64d69x50d61&P2=1&P1=1&G=ionic-squares&A=Blaz&B=Cerise_Talis&D=2022-08-10&T=Quickly_sketched W=10x10&L=d26d43d7d55x7x76d2x30&SS=27LLUURRDD6LLUURRDD7LLLLUUUURRRRDDDD31LLLLLUUUUURRRRRDDDDD14LLLLUUUURRRRDDDD&P2=1&P1=1&G=ionic-squares&A=Pedro&D=2022-08-11&F=2&K=CeriseTalis,Dohz&T=Gentle ## Expanded rules The rules were expanded on 02/12/2022, with the possibility of having more than one dot per square (parameter X), and even more than one square containing a dot (parameter Y), abbreviated as ´´ x • y ■ ´´ ### 2 dots per square, 1 square per dot (2 • 1 ■) W=7x7&L=d15d60d61d26&SS=4DDDDRRRRUUUULLLL23DDDRRRUUULLL&P2=1&P1=2&G=ionic-squares&A=Cerise_Talis&D=2022-12-02&N=6&T=Goldfishies W=10x10&L=d33d37d27d58d7d5d50d6d6d82&P2=1&P1=2&G=ionic-squares&A=Cerise_Talis&D=2022-12-02&N=7&T=Decadent W=15x13&L=d39d22d8d146d12d97d21d12d19d99d12d146d8d22&P2=1&P1=2&G=ionic-squares&A=Cerise_Talis&D=2022-12-02&N=8&T=Polycoria ### 1 dot per square, 2 squares per dot (1 • 2 ■) W=7x7&L=d45d76&P2=2&P1=1&G=ionic-squares&A=Cerise_Talis&D=2022-12-11&N=10&T=Gulls W=8x8&L=d83d84&P2=2&P1=1&G=ionic-squares&A=Cerise_Talis&D=2022-12-11&N=11&T=Bulls ## Acknowledgements and Changes **2022-08-10** Thanks to @Karoo, @Blaz, @Deusovi and @CeriseTalis for feedback on the current implementation and several suggestions to improve the input mode and error highlighting. **2022-08-11** Thanks to @Dohz and @CeriseTalis for finding a non-uniqueness in one of the puzzles. **2023-07-23** Thanks to @dohz for noticing the text of the first rule was missing, and for the clarification of the no vertex overlapping condition **2023-09-07** Thanks to @KuchiwoTsugumi and @CeriseTalis for noticing a loop interference bug, now fixed **2024-03-02** Thanks to @EliDoris for bringing the rule panels fo [Ionic Squares] into the [modern format|../panels#modern] **2025-02-11** :::Encoding [ionic-squares] parameter encoding and display was upgraded, so that the parameter now appears in puzzle pictures.
