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.

Verdict
The clearest difference is ads: 反射神経、思考力、記憶力 at none against Doors QA's shown. Doors QA's advantage is update cadence (every 2 days vs every 5 months) and iOS requirement (12.0 vs 15.1). On price, in-app purchases and device support there is nothing between them.
