Yukkuri Tap Coin Idle Game for Touhou is a free idle game available on iPhone that combines tapping and automatic gameplay mechanics. Players engage in a unique experience where they can shoot coins indefinitely while collecting skills through lucky bags. The game features over 10,000 types of AA character appearances, enhancing the collection aspect. Players can challenge bosses that appear at intervals, and if defeated, they have the option to rematch.

The game also allows players to enhance their tapping abilities by consuming experience points, which leads to character appearance changes and increased power.
