Slot Sort is a casual puzzle game where players remove layered metal plates by choosing the correct screwdriver tool for each screw. Each level has a different board layout with overlapping plates, hidden screws, and a target move count. Players tap or hold visible screws to loosen them, clear plates in the right order, and reveal a randomly generated pixel letter underneath. The app includes multiple handcrafted levels, a level selection screen, saved best times for each level, and a fastest-times leaderboard. The experience is fully offline, uses simple touch controls, and focuses on logic, observation, and completion time.
Guess The Scale
Read full descriptionHide full description
How big is it, really? Guess The Scale shows you a familiar object and a black silhouette of another. Pinch, drag or slide to resize the silhouette to its real-world size, then lock it in and watch it reveal in full colour next to the truth. Sounds easy until you try to picture a burger next to a smartphone, or Big Ben next to a dinosaur. ENDLESS Round after round of everyday objects, animals and vehicles. Strong guesses build a streak multiplier, and perfect rounds earn a bonus. Every 1,000 points is a new level. MEGA SCALE Every third round goes big: landmarks, skyscrapers and giant creatures, each with a short fact when it's revealed. DAILY CHALLENGE Five rounds, the same for everyone, once a day. PLAY A FRIEND Create a room and send the code, link or QR to a friend. You both play the same 7 timed rounds, then swap results to see who has the better eye. No account needed. Your progress stays on your device.
