THE GAME Fix EV3 Rover is a fun game where you get to program a robot vehicle using instructions loosely based on the LEGO® MINDSTORMS® EV3 programming languages. And now you can choose whether you want to use the older, icon-based language instructions or the newer Scratch-based language instructions. Completing each level of this game will help you learn basic programming techniques that are particularly useful for participating in FIRST® LEGO® League (FLL®) competitions. No robotic equipment or previous programming experience is necessary. EV3 ROVER’S STORY EV3 Rover is a robot vehicle sent on a rocket from Earth to the planet Nuftobor. Unfortunately a major solar flare occurred shortly after takeoff, erasing all programs from the robot’s memory. While EV3 Rover made it safely to Nuftobor’s surface, it cannot move on its own without programmed instructions -- instructions that YOU must provide! Your goal is to Fix EV3 Rover so that it can complete its mission of exploring its new surroundings. EQUIPMENT EV3 Rover is equipped with motor-driven wheels for moving and turning, a sensor to detect dark-colored ground beneath it, and a front touch sensor bumper to detect obstacles in its path. In later levels of the game you can program its scooper-arm to lift, carry, and drop boulders found on the planet’s surface. CHALLENGES You’ll face challenges that require logical thinking and spatial intelligence, while being guided through progressively more complex game levels. And if you forget the meaning of any programming symbols, you can easily look them up using the in-game symbol dictionary. Get ready for a fun and engaging adventure as you Fix EV3 Rover!

Verdict

The call

The clearest difference is update cadence: Spaceflight Simulator at every 9 days against Fix EV3 Rover's every 10 months. Spaceflight Simulator also leads on ratings volume (98K vs 9) and rating (4.8 vs 4.6). Fix EV3 Rover's advantage is monetization model (free vs free with in-app purchases) and review sentiment (100% vs 85%). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Fix EV3 Rover sells 1 one-off in-app purchase and Spaceflight Simulator sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Spaceflight Simulator holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Spaceflight Simulator has 98K ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 100% of Fix EV3 Rover's written reviews are positive against 85% of Spaceflight Simulator's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Fix EV3 Rover ships an update every 10 months, Spaceflight Simulator every 9 days. The most recent releases landed on October 3, 2026 and October 14, 2026 respectively.
