Mathler Cache Builder
Make your own daily Mathler math-puzzle cache with a sharable play link.
Mathler is a daily math-guessing game. You pick a difficulty, and your cache
serves a fresh calculation every day, like 20+7*3. A player sees
only the answer it equals (here, 41) and has to find the calculation. Every
guess must be the same length and must also equal that answer, and each tile
is coloured: green for the right digit or operator in the right spot, yellow
for one that belongs but is in the wrong spot, and gray for one that is not
used. Solving the day's puzzle reveals your final coordinates or keyword.
Miss it and they are locked out until tomorrow's puzzle. The equations and
the final answer stay on the server, so nothing is hidden in the page for a
player to peek at.
Save this link now. Without the key you cannot edit or delete this puzzle (only the site admin can reset it).
Your puzzle
Shown to players as a link to your cache page.
Your cache draws a new puzzle from this difficulty every day. Easy is short calculations, hard is long ones. You do not pick the equations, players get a fresh one daily.
Tries per day (4 to 10). Use them all without solving and the player is locked out until tomorrow's puzzle.
On solve, reveal
Shown only after a player finds your calculation. Reveal either the final coordinates or a keyword, not both.
