About this game
A quiet laboratory. A mysterious signal. Ten puzzles to bring it back to life.
Join Dr. Tom Cat in The Midnight Signal, a gentle puzzle adventure full of logic, numbers and discoveries. Read the clues, try an idea and discover how the answer works.
A COMPLETE TEN-PUZZLE ADVENTURE
Explore number patterns, honest and false labels, a rotating dial, equal weights, circuit paths, paired switches, ordering, binary lights and time. Collect four numbered seals and use your notebook to open the final lock.
LEARN AT YOUR OWN PACE
Every puzzle includes two optional hints and an explanation. Story mode has no timer, no penalty for trying again and no score pressure. Children can play independently or discuss the clues with a parent or teacher.
LAB CHALLENGE & LOCAL RECORDS
Try an optional timed replay. Earn up to 1,000 points, collect one to three stars per puzzle and unlock five achievement badges. Hints and incorrect checks reduce challenge points, with at least 50 points for each solved puzzle. Choose from six fictional explorer names and take turns on one device. Only complete runs are ranked: highest points first, then fastest time. Your best result per explorer stays saved when you restart the story. No online leaderboard or account is needed.
GREEK AND ENGLISH
Switch language at any time. Your answers, hints and progress stay saved on the device, so you can take a break and return later.
OFFLINE PLAY
All puzzles and artwork are included. No account, adverts, purchases, chat, external links or internet connection are needed to play. The game does not collect or share personal data.
FOR PARENTS AND TEACHERS
A short game for practising number sense and problem solving. Some children may benefit from help reading the clues. This is a practice adventure, not a curriculum or an assessment. Instructions for adults and privacy information are available in Settings.
The adventure has a complete ending. Revisit solved puzzles from the chapter map or reset progress for a fresh start.
Records remain on this device only. Clearing app data or uninstalling removes them.
