Suma App vs Sky Ace

Try to solve as many additions as you can. You have only one second for each operation! Good luck!

Sky Ace is an arcade flying game for kids. Press and hold to climb. Let go to dive. That is the whole control scheme — but it is not the whole game. No ads. No subscriptions. No purchases. Free to play, completely. A kid and his dad built this one weekend at a time, at the kitchen table. He drew the planes, picked the colors, named the worlds, and played every level until it felt right. His dad wrote the code. WHAT YOU GET All 10 levels across two chapters — Clear Skies and Storm Chaser. City Free Flight and Mountain Free Flight — open sandboxes with no timer, no fail state, and no goals. Landmarks to fly around, coins to collect, rings to chase. Runway Challenge, where landing is the whole point. Every plane, every mode, every level. No gates. WHAT WE DO NOT DO No ads. No subscriptions. No purchases of any kind. No account required. No email. No data collection of any kind. No tracking. No social features, no chat, no friends list, no leaderboards that show real names. No links out to websites or stores. That list is complete. We did not leave anything out. PARENTS Sky Ace is listed in the Apple Kids Category for ages 9 to 11 and follows Apple's guidelines for that category without exception. Nothing your child does in the app leaves the device. We do not have a server. We could not look at your kid's progress if we wanted to. WHY WE BUILT IT He wanted a flying game that did not nag him to watch ads, did not push him to buy coins, and did not ask him to log in before he could play. He could not find one. So we made one. GAME MODES Runway Challenge: the newest mode and the hardest thing in the game. Guide your plane on final approach, watch the landing gear come down, follow the flashing runway lights, and try to touch down just right. Smooth landing earns the Pilot of the Year badge and 50 coins. Rough landing means you survived. Too fast, and you are coming around again. Missions: 10 hand-crafted levels across two chapters — Clear Skies and Storm Chaser. Obstacle courses, time trials, and coin chains. Levels unlock in order. Each earns up to three stars. Free Flight: two open sandbox worlds with no obstacles, no timer, and no fail state. City landmarks or mountain peaks — go wherever you want, collect coins, and hit boost rings. PLANES Four planes designed by a kid. Each has distinct speed, handling, and armor. The starter plane is free. The other three unlock with coins earned through play. Upgrade any plane across three tracks: engine speed, wing handling, and armor plating. CONTROLS Press and hold to climb. Let go to dive. Thanks for taking a look. If your kid laughs once while playing, we did our job. A dad and his kid.
