Hey, thanks for playing the game. I apologize if the game objective wasn't clear (it's an issue we been running into with a lot of players lol). But you are supposed to score WITHIN that percent range of the Goal. So, as per your screenshot, being WITHIN 25% of 155 would mean you have to score between 116.25 and 193.75 (Rounded up of course). And within 10% of 155 would have to be scoring between 139.5 and 170.5
I know it's an abstract mechanic, since most similar games are usually just "score above this value," but we liked the idea of getting as close to a target number as possible so that the gamba is more strategic and you can't just press the highest number buttons.
