Sparkora: Matchstick Puzzle

Move one match and the sum works. 120 solver-checked levels, a shared daily puzzle, and a Lab that finds every answer to any matchstick riddle you feed it.

A sum built out of matchsticks that does not add up. Move exactly one match and it does. That is the whole game — and the moment you finally see it, it looks obvious.

6 + 4 = 4 is wrong. Lift one match off the six, lay it back down, and suddenly it reads 0 + 4 = 4. No trial and error, no luck: just the small click in your head when the answer arrives.

THE MATCH LAB — POINT IT AT ANY RIDDLE

• Saw a matchstick riddle on a napkin, in a group chat, on a social feed? Lay it out here
• Pick the rule — move one, move two, add one, take one away — and get every single answer
• The search is exhaustive, not a guess: when it says there is no answer, no answer exists
• It runs entirely on your phone, in a fraction of a second, with no connection
• Nothing else settles an argument about a matchstick riddle this fast

120 LEVELS, EVERY ONE CHECKED BY THE SOLVER

• Six chapters that heat up from First Spark to Inferno, twenty puzzles each
• Early chapters forgive you with several possible fixes; the last ones demand the one right move
• A closing chapter where a single match is not enough and you have to move two
• Every shipped puzzle was verified solvable before it was written to the app, so you are never stuck on something broken

A FRESH SPARK EVERY DAY

• One shared puzzle a day, identical for every player on earth, built from the date alone
• Monday is gentle, the week heats up, and Sunday is a two-match day
• Build a streak and watch the month fill in on the calendar
• Share how fast you cracked it with a single tap

HONEST HINTS, NOT A PAYWALL

• Ask and the coach points at the exact match to pick up; ask again and it shows where it goes
• The first hint of every puzzle is free
• Undo and restart are always free, unlimited, and cost you nothing — a mistake is never the end of a board
• No timer rushing you, no lives to run out, no move limit to fail

SEE HOW ELSE IT COULD HAVE BEEN DONE

• Solve a puzzle and the app lays out every other legal fix in matches, not in text
• Some puzzles have one answer, some have four, and knowing which is half the fun
• It is the fastest way there is to learn the tricks: a plus is only a minus with one extra match
• Ten becomes nine, six becomes zero, five becomes six — you start seeing the moves before you make them

STATS BUILT FROM REAL PLAY

• The share of puzzles you cracked with no hint at all, which is the number worth chasing
• A solve-time trend across your last ten puzzles
• A consistency heatmap of the last fifteen weeks
• This week against last, your best day of the week, and your personal records
• 40 badges across 10 families, from your first solve to a hundred-day streak

PERFECT FOR

• Anyone who likes a brain teaser with one right answer rather than a lucky one
• People who grew up on matchstick riddles in newspapers and puzzle books
• Parents and teachers looking for real mental arithmetic that does not feel like homework
• Commuters, waiting rooms, long flights: it never needs a signal
• Anyone who has ever stared at a matchstick riddle online and wanted to know for certain whether it even has an answer
