#41 - Tentaisho / Star Battle Hybrid

     This puzzle is mostly a proof of concept, which is why it's so small and isn't very logically interesting. I've seen several attempts at a Tentaisho Star Battle hybrid, but I've seen no successful ones without additional rules. My ultimate goal is a 10x10 one with two stars, but the best I've managed so far is a 6x6 one with one star.

    Divide the grid into regions of orthogonally connected cells. Each region must contain exactly one circle and have 180° symmetry around it. Additionally, place stars into some cells such that each row, column, and outlined region contains exactly one star. Stars may not touch one another, not even diagonally.

    Hi Eric, I've made a 12x12 star battle tentaisho hybrid (without any additional rules) yesterday. It was very hard to make, and the deductions are not fantastic, but it works and has a unique solution.

    If you find the time to play it, and/or need a printer-friendly version, please let me know!

      Impressive! The next goal would be to make one which doesn't resolve uniquely as a Tentaisho alone, so that you have to use the genres together rather than one after the other. I may come back to this and attempt it soon (probably with an 11x11).

    I hope the following puzzle would prove the concept for 2-star puzzle. https://swaroopg92.github.io/penpa-edit/?m=edit&p=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

     For my 300th post, I've put together a collection of example puzzles for all of my original puzzle genres. As I create more in the future, this post will get updated. I hope you enjoy!     1.  Ovotovata  (oh-VOH-toh-VAH-tuh)      Draw a non-intersecting loop through the centers of some cells which visits each shaded region at least once. When the loop exits a clued region in any direction, it must travel in a straight line for exactly the indicated number of cells (turning on the Nth cell, where N is the value of the clue).

Regions with numbers must contain the indicated amount of shaded cells. There may not exist a run of more than three consecutive shaded or unshaded cells horizontally or vertically anywhere in the grid. Solve online
