山川氏によるスマホ詰将棋第3弾です。 今度は曲詰めオンリーの30作としました。「曲詰」とは詰上がりまたは初期局面がなんらかの形になっている詰将棋を言います。 (※とはいえ最終手余詰めの都合で形ができない場合もあります。) 形だけでなく手順も非常に洗練されておりますので、通常通り読みの訓練にもなるでしょう。将棋ゲームとしてやるのも良いでしょう 皆様からの挑戦をお待ちしております。 ※途中でアプリを落としても、続きからチャレンジできます。 山川さんのブログへのリンクもあります。 ーー詰パラモバイル管理人による詰め将棋級、段ーー 一週間で30問解けたら、スマホ詰将棋4段を認定します。 さらに曲詰初段を認定します。(?) ーー操作方法ーー 「詰将棋を解く」をタッチすると作品が表示されます。 攻方の駒をタッチすると選択状態になりますので、移動させたい箇所の盤上をやはりタッチします。 正解手ならば玉方が自動的に対応してくれます。不正解ならばその場で初手からやり直しになります。 ーールールーー (1) 攻方は王手の連続で玉を詰ますこと (2) 攻方は最短最善手順で玉を詰ますこと (3) 玉方は最長最善手順を選んで逃げること (4) 攻方の持ち駒以外の駒は玉方が使用できる (5) 攻方は詰手順中の入手駒を使用できる (6) 他は全て指将棋のルールが適用される (6-1) 二歩を売ってはいけない (6-2) 打ち歩詰めは禁手(突き歩は可) (6-3) 行き場所の無い駒は打てない (6-4) 王手の千日手は不詰 (7) アプリ内でのこと (7-1) 同一局面王手があった時点で不正解 (7-2) 最終手にて、3手以上かけると不正解扱い ーーアプリ&作者についてーー 皆様こんにちは、詰将棋パラダイスモバイル版の管理人をしておりますエモンといいます。 人気詰将棋作家山川氏による詰将棋集第三弾です。珍妙な解説は再び私です。 今回はなんと全て曲詰!なんという技術でしょうか!信じられません。出てくる文字に感嘆しながら楽しみましょう! ーー最後にーー 我々を楽しませてくれる、詰将棋作家さんたちに最大級の敬意と感謝を。

Just Sum! Number Logic Puzzle

Features
Read full description

Pick the numbers to keep. Land every sum exactly. Just Sum! is a calm number puzzle built on one simple idea: every row, every column and every colored area has a target sum. Tap the numbers you want to KEEP, leave the rest behind, and the moment all your sums match, the level is solved. You never have to guess. Every board is generated the moment you start it and verified by a solver, so there is exactly one solution — and pure logic will always get you there. HIDDEN ? CELLS From level 31, some tiles hide their number behind a "?". You still have to decide whether to keep them, using only the sums around them. Get it right and the number is revealed. It is the twist that keeps the bigger boards interesting. FEATURES • Endless levels that grow from a cozy 3x3 up to a demanding 10x10 • Every board freshly generated with a guaranteed unique solution • Hidden ? cells unlock as you progress — from one per board up to six • No timer, no lives, no game over. Mistakes are counted, never punished • Stuck? Trade a rewarded ad for a hint that solves one cell for you • Stats kept on your device: highest level, clears, flawless clears, best time per board size, total play time • 7 achievements to chase, from reaching level 10 to 100 total clears • Warm rounded visuals, with a dark mode that is genuinely bright and easy on the eyes • Rich haptic feedback on every tap, every mistake and every completed line • Boards are generated on your device, so you can keep playing offline • iPhone and iPad, in English, Japanese, Korean, Spanish, Simplified and Traditional Chinese HOW TO PLAY 1. Tap a number to keep it. Tap it again to undo 2. Match the target sum on every row, every column and every colored area 3. The numbers you never tap are the ones you erase 4. When all the sums line up, the level is clear Thirty seconds or thirty minutes — pick up where you left off, and make it add up. Free to play, supported by ads.
