Idle Study is a free-to-play clicker game developed by 10BILL for Android devices. The game's primary goal is to help players improve their English, Spanish, and math skills while making money. Players can press and hold the screen instead of tapping it, which adds a unique twist to the traditional clicker game formula.

As players progress through the game, they can build an academy, hire tutors, and upgrade their study space. Additionally, players can change the appearance of their character, Billy, by choosing from a variety of available clothes. The game's graphics are cool, and the quality is higher than most idle games. However, players must remember to save their progress in the options pop-up to avoid losing their data.
