どこチェン - がんばれルルロロの脳トレ アハ体験 is an educational game developed by RedApps JP. It is available on the Android platform and is free to download.

The game features a series of 150 puzzles where players have to find the differences in gradually changing illustrations. Each of the 30 illustrations has 5 different questions, providing a total of 150 brain-training challenges.

There are two game modes available: Normal Mode and Select Mode. In Normal Mode, players solve randomly generated puzzles and can use the replay function if they are unsure of the changes. Each play allows for 5 replays, and there is a recovery feature in case replay counts run out. Select Mode allows players to replay previously cleared puzzles from Normal Mode and aim for higher scores.

With cute illustrations from the popular anime "Tiny twin bears" (ルルロロ), this game offers a fun and engaging way to train your brain. Join the adorable world of ルルロロ and challenge yourself with brain-training puzzles!
