巨大な扉を開ける。 それだけで、冒険が動き出す。 封印扉の向こうに待つのは、財宝か、敵か、罠か、それとも未知の何か。 1タップで扉を開き、現れた結果を見て「持ち帰る」か「さらに潜る」かを決めよう。 深く潜るほど報酬は大きくなる。 けれど、危険な結果に遭えば財宝を失うこともある。 安全に帰るか、次の扉に賭けるか。決めるのはあなただ。 【ゲームの特徴】 ・巨大な封印扉を1タップで開く、シンプルな操作 ・宝、敵、罠など、扉ごとに変わる予測不能な結果 ・財宝を100%確保する「持ち帰る」と、報酬を狙う「さらに潜る」 ・封印鍵、護符、扉機構の3つに絞った拠点強化 ・扉の自動設置、自動開扉、放置中の大扉発見が段階的に解放 ・最高の一撃は手動開扉に残る、放置と操作のバランス 強制広告はありません。 動画広告を見るかどうかは任意で、視聴しなくても遊べます。 アプリ内課金はありません。 さあ、最初の封印を砕け。

Pull, aim, and set the mechanisms in motion. Pull down and release the golden plunger to launch a silver ball. Fill three holes on each of six mechanical boards: a windmill, a clockwork bridge, drums, a pendulum, twin gates, and a star-themed board. Watch the moving mechanisms and adjust your launch strength. Completed holes remain filled during the same attempt, and the meter remembers the previous shot. Choose one charm: attract the ball near a hole, rebound it from the bottom, or slow it down. On normal boards, a charm can be used once per attempt. Watch for the ready indicator; pressing before launch or outside its range does not use it up. Beat your fewest-ball record on each board, with separate records for unused charms and each charm type. Retry the same board after clearing it. Clear the first three boards to unlock Night of the Hundred Demons. Start with 14 balls and aim for eight floors, choosing routes and upgrades while damaging enemies through physical contacts and goals. The game is free to download. Boards and charms unlock through play without additional purchases. If Remove Ads is not owned and tracking permission and regional privacy conditions allow it, ads may appear after a clear. Declining permission or an unavailable ad does not prevent continued play. Remove Ads is an optional one-time purchase. Previous purchases can be restored. The purchase screen displays the price in your store's currency. Purchases and restoration require a network connection. Progress, records, equipment, sound settings, and the current special-mode run are stored on your device. No game account or cloud synchronization is required.
