No ads! No charge! Super hyper casual Amida game!! """ Ofu. It's a Japanese noble food. The Japanese have long believed in Ofu and have faith in Ofu. However, it is the noble creature, the carp, that eats the noble Ofu. Japanese people have lived with Koi, means carp in Japanese. The Japanese was able to gain prosperity by offering Ofu to Koi. However, because Ofu was noble, the freshness was severe, and Koi was also sensitive to the orbit of the Ofu. We have to pick up this app and steadily deliver Ofu to Koi. How loyal can you be to Ofu and Koi? "" " This game will be a game to complete the Amida-kuji, which is a Japanese traditional pazzle game, and deliver the Ofu to Koi! Only one Amida line can be drawn per turn. What kind of line is drawn at which position becomes very important. Moreover, the time limit is only 5 seconds! If even one Ofu doesn't reach the mouth of Koi, the game is over ... With a ranking function, let's enjoy the rivals and the OfuLine all over the country!!

[A Fun New Math Game Appears!] Controls are a breeze: just tap the moving math symbols! Calculate repeatedly to reach the goal number. Even though it's a math puzzle, you can grab items and choose from 3 power-ups. Do that, and you can control the math exactly how you want! Before you know it, you might just get completely obsessed! [How to Play] Touch the math symbols moving across the screen! That symbol will then calculate the two numbers in the center. Calculating creates new numbers and symbols, so touch them again to calculate with your previous answer. The appearing numbers and symbols are random, so there's no single set answer! Calculate over and over to create your target number. If your calculated number is a "Multiple of 10" (10, 20...), "Ends in 7" (7, 17...), or has "Matching digits" (11, 22...), you can get an item, or "Keep" a symbol in the top right corner to use whenever you want! There's also plenty of support during the game! Check the "Next" display for upcoming symbols and numbers. Use the "Shuffle" button to change your Next items! When the screen is full of the same symbol, an item appears that lets you summon that symbol later. If the screen gets cluttered with items, use the bottom left buttons to toggle the display or shake them up. [Game Modes] There are two game modes: "Calc30", a light mode where you calculate to make 30, and "Calc-Trip!", where you make multiple numbers in any order you like. In "Calc-Trip!", 3 choices appear every time you make a number! You can power up by changing numbers, symbols, or getting items. As you advance through stages, special gimmicks trigger when certain numbers are made. Sometimes it makes your next moves harder to read, and sometimes it makes them easier. Challenge yourself with all kinds of calculations! [Recommended for] Highly recommended even if you're not good at math! You don't need to get the right answer on the first try here! Use items, calculate repeatedly, and you might just become a math pro?! And of course, highly recommended for those who already love math! Pick the right power-ups, overcome the gimmicks, and aim for a new clear-turn record! The tutorial (for Calc30 mode) comes in a quick Short version, as well as a detailed Long version. It also supports a wide range of 13 languages, and lets you switch between region-specific symbols like × and *, or ÷ and /. Math is a universal language—let's all enjoy it together! Come fall down the fun math rabbit hole!
