Three Digits

非常可怕的一个游戏，说是游戏倒不如说是无聊透顶的数学题，足足300道，抱着负责的态度看着攻略哭着做完，真不知道自己当初是怎么加进库的，希望steam下次别再给我推这类。另外通完会马上删除+隐藏，永远不想看见它

The game is alright, I would give it a neutral review but since Steam has only positive and negative reviews I'll select positive, since as of this edit the game had below 50% positive reviews. I got this game a while ago and got the badge but I've only just properly played it now and there are some issues I've had with the game. - As a quality-of-life feature, the game could really do with an undo button or a save board state feature. - The reset button is very slow, it's faster to manually remove the red/green from all of the numbers and manually reset that way. - The game doesn't exactly have a consistent difficulty curve as it seems to top out for full rather quickly and most of the variations are less difficult than full. To make the difficulty curve more gradual I would say to have full be at the end and have the variations building up to full in terms of complexity, or to have full near the end and then levels such as Awkward Range Reversed afterwards at the end. - There are a few big blocks of the same level type in the game, e.g. the section full #3 is 60 full levels in a row which is a bit much at least for me and gets samey rather quickly. 30 of the same type in a row I would say is a good maximum but 15-24 is a nice block size. - The textures don't seem to scale well to higher resolutions, this is most noticeable on the scrolling icon on the level-select screen, however since this game is rather old by now this isn't too unexpected and not too much of an issue anyway. - The background music doesn't save its configuration when you exit the game, so it will always load turned on and at maximum volume. - It would be cool if the random mode allowed more options, such as numbers of only a certain category (e.g. multiples of 3, primes, etc.). Bugs: - The achievement rewarding is wonky and requires you to close the game, reopen the game, then close the game again to be awarded with them. - The game seems to lag when kept open for a while, especially when in a larger resolution and when a lot of numbers are clicked on and off. - When you beat Level 300 (the final one), the game displays Level 301 at the top briefly and then kicks you to the main menu after that. - The random mode says you must have a difference of 29 to make a board, however it seems to be that you actually need a difference of at least 299. - The random mode doesn't let you input exact numbers and so the scrollbar doesn't let you pick exact values and will skip over some on many resolutions. - The save slot and how to play info text goes slightly off the screen on 800x600, it's still readable but some of the letters have the very end cut off. I would say if you don't mind the premise of the game and don't mind it getting samey/repetitive it's fine to go through every-so-often, but otherwise probably not.
