## What kind of game is it? Osumo Tap is a casual Japanese-style tap game that you can enjoy with one finger. Tap the wrestlers that appear one after another, avoid the referee, and see how long you can keep going while building your score. As you keep tapping, you can enter rush mode for bigger scoring chances, and wrestlers appearing higher on the screen are worth more points. On top of that, grabbing salt triggers the Shio Whirlwind, which makes the referee retreat for a short time and gives you a chance to recover your run. ## Highlights of this version - A more engaging scoring rule where points change depending on tap position - Comeback opportunities through the Shio Whirlwind triggered by salt - Progress features that let you look back on today's best and your last 7 days of records - A new banzuke progression feature that lets you check your current rank on the start screen and view the full rank list at a glance - Promotion banners on the result screen that make daily score updates and rank progression easier to enjoy - Daily timer and settings protection flows designed to make playtime easier to manage and safer for families ## Recommended for players who... - Want a game they can play quickly in spare moments - Want something safe and easy to enjoy with children - Like relaxed Japanese-style game worlds - Enjoy improving daily records and chasing higher scores - Enjoy steadily building up rank progress and personal milestones It is a simple tap game that is easy to keep playing, with the fun of gradually improving your daily best and raising your banzuke rank over time.
