Read full description

This is a clock game. You can play with your kids,study with your kids,play like a puzzle game. It's a simple game, but it's difficult to get a high score. Wouldn't you like to know your limits? How to play --- Read the time and enter your answer using the numeric keypad. If you get the answer right, a new question will be asked. When the timer reaches 0, the game ends and your high score will be displayed. Touch the clock on the screen before the game starts to display a menu. You can change the game settings. You can choose from 4 types of games. ・Questions are asked randomly in Game 1. ・Game 2 starts at 8am Questions are asked approximately every 15 minutes. In baseball terms, it's like knowing the course but not known pitching... That's the mode. However, you can roughly predict the ball, so you can play without stress. ・Game 3 is Game 2 with a time limit per question. New questions will be asked after the time limit has passed. ・Game 4 is a completely patterned game. It starts at 8am and the time changes every 15 minutes. Everything is decided, so you don't even need to look at the screen. But sometimes you get it wrong, so you need to check it regularly... That's the mode. Everything is planned out, and there are no coincidences in the game, but it's interesting for some reason... That's the mode. Even though it's a quiz game, it's natural to get one question right every two seconds... If you're good at it, you might be able to get one question right every second. In my opinion, the theoretical high score is a maximum of 180 points... The initial setting is Game 2. ---- You can set whether or not to have a second hand. If you prefer a speedy game, select no second hand. ---- You can set whether or not to have operation sounds. ---- We have also prepared a "Hiragana" mode so that small children can play together. In "Hiragana" mode, the clock time changes when you enter the time. You can choose to display the game screen in Hiragana or Kanji. ---- If you touch AC three times on the screen before starting the game, a high score reset menu will appear. High scores are set for each game mode. You can reset the high score for the game mode you are currently playing. ---- General knowledge and things that you do every day are often wrong if you ask them over and over again in a timed manner. We made a game out of that. It may look like an educational game or a game to prevent dementia, but even for adults, it is quite difficult to seriously aim for a high score. How many questions can you answer in 3 minutes? Give it a try!
