Look at the mental arithmetic problem on the top panel, go through the correct door on the stage, and complete the level by finishing within the time. When you clear a level, you can advance to the next level and your score will increase rapidly.
- The player who keeps running toward the back of the screen can move left and right by dragging.
- The question will be displayed on the top panel, and at the same time the answers (one correct answer) will be displayed on two to four doors on the stage.
- Players can only pass through the correct door, and their score will be added as they pass through.
- If a player hits an incorrect door, they will be bounced backwards and lose time.
- If you reach the goal within the time limit (initially 30 seconds), the level will be cleared and the remaining time will be added to your score.
- If your score is within the top 20, the high score screen will be displayed, displaying a list of the cleared date, time, level, and score.
- A level has multiple stages, and each stage has a set of answer doors.
- Time will be added if you get a potion that is randomly falling on the stage.
- As you clear the levels, the number of stages increases and becomes harder to clear.
- If you can’t clear it within the time, it will be “game over”. (If your score is within the top 20, the high score screen will be displayed)
- You can also pause or end the game by tapping the “X” button on the top right.
