木のスコップ1本。掘削速度、毎秒1cm。 目標は、地球の中心——6,371km。 このままでは到達まで176,972時間13分20秒。約20.2年かかります。 DIGGERは、その絶望的な数字を削り倒していく放置系クリッカーです。 ■ 掘って、稼いで、強くする 画面をタップして掘る。掘った深さぶんコインが手に入る。コインでツールを買い替え、掘削出力を上げる。 木のスコップ → 石のスコップ → 銅のピッケル → 鉄のピッケル...。 20年かかるはずだった穴が、みるみる深くなっていきます。 ■ アプリを閉じても、男は掘り続ける 放置系なので、寝ている間もオフラインで掘削は進行。起きたら成果を受け取るだけ。 「オフライン作業員」を強化すれば、放置効率と上限時間が伸びていきます。 ■ 深さは、実在の記録とリンクしている ・42.3m —— 都営大江戸線 六本木駅(日本一深い地下鉄駅) ・240m —— 青函トンネル最深部 ・634m —— 東京スカイツリーがすっぽり沈む ・1,000m —— スーパーカミオカンデ ・3,776m —— 逆さ富士、完成 ・10,920m —— マリアナ海溝チャレンジャー海淵より深く ・12,262m —— コラ半島超深度掘削坑。人類が掘った最も深い穴 ここから先は、誰も到達したことのない未知の領域です。 記録を突破するたびに、科学の雑学ポップアップとボーナスコインが手に入ります。 ■ 地球の内部構造も、実際のとおり 土壌 → 粘土層 → 堆積岩 → 花崗岩 → マントル → 外核 → 内核。 深く潜るほど景色が変わり、コインの価値も跳ね上がる。 モホロビチッチ不連続面、グーテンベルク不連続面、レーマン不連続面——教科書で名前だけ見たあの場所を、自分の手で通過していきます。 ■ 地球を掘り抜いたら...? さらにその先へ。半径はすべて実際の天文学的数値です。 ■ 桁が壊れていく快感 K → M → B → T…… 数字はやがて10の63乗を超え、指数表記になります。 掘削出力とコインの価値は実質無限にレベルを積めるので、進行が止まりません。 ■ 遊び方はシンプル ・放置:何もしなくても掘り進む ・タップ:連打で追加掘削。心地よい音と手応え付き ・ショップ:ツール17種とアップグレード6種 ・ブースト:広告視聴でフィーバー/タイムワープ/コインフィーバー/タップラッシュ(任意) ■ こんな方に ・コツコツ数字が増えるのが好き ・放置ゲーム、クリッカーゲームが好き ・宇宙や地球科学が好き ・通勤中や寝る前に、少しだけ触りたい アプリ内課金はありません。広告つきで、すべて無料で最後まで遊べます。 さあ、掘りましょう。 地球の中心には、何が待っていると思いますか?

Manage a peaceful Japanese hot spring inn alongside 50 charming yokai companions in this cozy idle simulation game! Even while you are away, your inn collects Yudama (in-game earnings). Expand bathhouses, renovate facilities, and restore a forgotten mountain retreat at your own gentle pace. There is no paid random gacha and no paid gameplay currency. You choose which yokai candidate to invite. Deep in a misty mountain valley stands an abandoned bathhouse. A Kappa scrubs the cypress tubs, a Bakeneko fluffs the futons, and a Chochin-obake lantern lights the path for travelers. As the Innkeeper, build a welcoming hot spring retreat with your friendly yokai staff. ■ Cozy Idle Progress: Earn While You Rest Your inn gathers Yudama while you work, study, or sleep. • Offline earnings accumulate for up to 8 hours initially. Renovations can permanently extend the limit. • Return to collect Yudama, upgrade facilities, and check on your yokai. ■ 50 Distinct Yokai to Collect & Assign Yokai work across five roles: Bathkeeper, Room Attendant, Chef, Gatekeeper, and Parlor Attendant. • Meet folklore favorites including Kappa, Yuki-onna, and the Nine-tailed Fox. • Discover their personalities in the Yokai Record: Akaname sees bath cleaning as a midnight snack, while Amanojaku welcomes guests by telling them to stay away! • Match staff to ideal roles for a 1.5x efficiency bonus. • Collect 48 Emaki scroll scenes: 38 regular scenes and 10 rank or seasonal outfit scenes. • Earn rank outfits as bonds deepen. At Old Friend rank, unlock each companion's Nishiki illustration and three-page story. ■ Generational Renovations & Prestige Develop 13 facilities and renovate when your inn's reputation reaches key milestones. Carry forward Spirit for permanent enhancements on the Spirit Tree. Watch your bathhouse grow across six generations, with grander buildings and changing mountain views. ■ Direct Recruitment at the Yokai Shrine: No Paid Gacha Choose a candidate and recruit that exact yokai with earned Yoki and a recruit slot. Slots recharge by 1 per day, up to a bank of 14. One optional ad-supported slot refill is available each day. While newcomers remain unowned, an extra introduction appears when none is among the regular candidates. Home-screen guidance points to an available recruit. ■ Two Ways to Welcome Guests In Woodland Baths, match animal groups to two baths by water temperature and group size. Plan at your pace across five turn-based stages. Record nine species, including mystical visitors, in the Woodland Guest Book after a satisfying visit. Earn Yoki for milestones, with no Yudama cost to play or retry. Classic hospitality also remains: choose the yokai best suited to a guest's request and earn rewards for successful service. ■ Transparent, Player-Friendly Design • No paid random gacha, paid gameplay currency, forced interstitials, or banner ads. Rewarded video ads are optional. • The one-time Video-Skip Talisman lets you claim eligible rewarded bonuses without watching videos. Daily caps, reward amounts, and conditions remain unchanged. • Preview Seasonal Sets before purchase. Outfits and decor are visual only; they do not affect stats, income speed, or progression. • Each of five Seasonal Sets covers outfits for all 50 yokai. If you already own a matching Seasonal Set, the newcomers' outfits are included with no extra purchase. Legacy signboard and noren artwork-only products are separate from outfit sets. Morning bath, midday soak, evening dip. The water is warm and ready. Welcome home to Hyakki Onsen.
