A very clever puzzle that puts a refreshing twist on Sudoku. It’s simple, minimalist, and smartly designed, turning familiar logic into something new and satisfying.
Fun Sudokulike game. The linux version didn't work, but windows+compatibility did.
[url=https://store.steampowered.com/curator/43083373/]Clever games curator review: 6/10[/url] A novel variant on Sudoku that I think would be far more fun to play with pencil and paper than using a computer. The reason is that when solving a moderately complex puzzle you need to logic through all the implications of your choices. Making notes about what possible numbers can go in which cell is a very useful way to do that. Plus the spatial nature of this variant, with overlapping cells and constraints, strongly encourages sketching out possible solutions. The game has no way to do this and I was frequently left feeling that I would actually be happier if I just took a screenshot and tried to solve it using MS Paint. I don't know if it would be possible to modify the game to make it significantly more usable than MS Paint would be. But I feel like there hasn’t been much of an effort to do better than the bare minimum, which is allowing you to put numbers in the cells, or not. To be honest it’s possible that the game does offer some ways to freeform annotate the puzzles, but the interface is quite inscrutable with symbols that don’t make clear sense, buttons that don't seem to do anything, and no real help functionality. I feel like they put a lot more effort into puzzle design than UI design. Too bad. I feel like this one had potential. Still weakly recommending it, based purely on the strength of the puzzle design, and only for people who like to do all of their puzzle solving purely in their head.
希望:カーソルを数字枠に当てた時、数字枠だけじゃなくて、サークル枠もフォーカスしてほしい。 (問題:解決しました) キーコンフィグで、間違えて他のボタンに「決定」を割り当ててしまったら、「決定」に何も割り当てられていない状態になってしまって、ページをめくることしかできなくなってしまった。。ミスった。。 以下の操作で解決した。 1. Escキーを押してオプションメニューを開く 2. Q or Eでタブ移動する 3. キーコンフィグ画面でF11キーを押して、キー設定をリセットする マウスを使用せずにキーボードのみでゲームをプレイしたいのだが、どうすれば良いのか分からない。 クイック移動にキーを割り当てても、制限された範囲?にしか移動できない。 分かる人いたら教えてください。
