Recently I designed a calendar puzzle with 10 tetris-like pieces. When you place all the puzzle pieces on the board, three squares/rhombuses are still open and together they form a date. Can you arrange the puzzle pieces in such a way that it shows todays date? See https://praxispuzzles.com/calendar_puzzle_rhombus Disclaimer: I sell these puzzles for a little more than the raw material.
Fun! Very similar to https://www.dragonfjord.com/product/a-puzzle-a-day/
I got this for my mother and she loves it, but it’s bloody hard some days! Great bit of kit though for any puzzle lovers.
Very cool!
Unfortunately the interactive demo doesn't work for me (Firefox 143.0.4 on Windows):
> Uncaught TypeError: can't access property "inverse", this.puzzlemat.getScreenCTM() is null
Can you arrange them to make dates that don't exist, or is it designed so you can't?
This is quite clever.
I love this. Do you ship to the US?
