コレって何だっけ is a free trivia game developed by MASK LLC. for Android devices. The game collects objects that we may have seen before but can't quite remember their names. It includes items found in bento boxes, in parks, on roads, and more. While not knowing these objects may not cause any inconvenience, knowing them might give you a slight advantage.

The gameplay is simple and enjoyable. Players read the questions, examine the illustrations, and tap on the location they believe is the correct answer. If they choose correctly, they move on to the next question. The game features background music and sound effects from Effect Lab and Pocket Sound, adding to the overall experience.

If you're looking for a lighthearted trivia game that challenges your memory and knowledge of everyday objects, give コレって何だっけ a try on your Android device.
