Set up a realistic field on your desk with AR. Aim at the opponent's position while defeating the enemy! □ Features ・Realistic graphics - Enjoy the sight of small tanks fighting on your desk. ・Up to 8 players can connect and play against other players nearby. ・Programming - In the latter half of the stage, you can control the tanks by creating programs with blocks. The game is intuitive and fun to learn programming. ・Free, no ads - Enjoy all content without paying. You can enjoy all the content without paying for it, and there are no ads, so you can play without stress. □ Cautions ・This application uses a technology called "feature point extraction" for plane recognition when displaying fields. Due to this characteristic, the application can be expected to operate relatively stably on planes with patterns, such as a wood-grained table, but the fields may not be displayed well on planes with few feature points, such as pure white tiles. Please be aware of this. ・Access to a camera and local network is required for use.

In the lab's petri dish sits a tiny seed — and it has eyes. As a researcher, your job is to observe it and help it grow. ■ The combination of stimuli changes what blooms Water, light, warmth, vibration and stillness. The two stimuli you give most decide which flower blooms. The same care on a different seed brings a different flower. You won't know what it is until it blooms. ■ Every seed has likes and dislikes It hops happily at things it likes and turns away from things it dislikes. Watching its reactions is the shortcut to rare flowers. ■ It keeps growing on its own Your seed grows slowly even while the app is closed. Left alone it blooms in about 3 days; check in often and it can bloom in about a day. Add more dishes to grow several seeds at once. ■ The Seed Vault and the Gold Tube New seeds arrive from the Vault every day. Open a Gold Tube for a special seed that grows into an unexpected creature instead of a flower. ■ Crossbreeding Pick two flowers from your Research Log and cross them. Only a good match gives a "Hybrid Seed". Which flowers go together? That's for you to find out. ■ Catalog and Journal Everything that blooms or hatches is kept in your Catalog — more than 500 kinds. Your Journal remembers what bloomed and when, and you can name each one you grow. The more you find, the higher your researcher rank, with gifts from the lab along the way. ■ Lab friends Connect with friends by Lab ID and send each other Growth Boosters. ■ Daily research A 7-day login bonus that gets better every round, and three new research themes every Monday. ■ Home screen widget Check on your seed's growth without opening the app. · Free to play (in-app purchases available) · Some features are available by watching ads (research videos)

Verdict
The clearest difference is in-app purchases: Scriptank at none against Mystery Seed Lab's 7. Scriptank also leads on ads (none vs shown). Mystery Seed Lab's advantage is update cadence (every 6 days vs monthly). On price, device support and iOS requirement there is nothing between them.
