Memory Flip-Stone

Want to check your brain capacity, improve your short-term memory and enhance your brain power? Try this with a cute wizard cat and have fun!
Simply tap each rock to flip and reveal, try to memorize where the engraved cat faces were and reopen those. If you flip the wrong one, red rock will show up. That's still okay. You still have chance. The cat will tell you how many chance you have left on the screen. Let’s do it before your brain gets hard as stone.
