《青蛙跳》是一款以經典「過河跳木樁」玩法為核心的 HTML5 休閒小遊戲，畫面採用色彩鮮明的叢林、沙漠與夜色三種主題場景，搭配流暢的 Canvas 動畫與趣味音效，帶來輕鬆又耐玩的遊戲體驗。
操作非常簡單：按住螢幕為青蛙蓄力，蓄力時間越長，跳躍距離越遠；鬆開手指後青蛙便會躍向前方，落在下一根木樁上即可繼續前進，若不慎落入水中則本關失敗。遊戲共設計了 16 個風格各異的關卡，從入門到高手循序漸進——隨著關卡推進，木樁會變得更短、更高低錯落，木樁之間的距離也會拉大，需要更精準地掌握蓄力時機才能順利過關。每個關卡都有 30 秒的時間限制與固定的過關目標，只有在時間內跳過足夠數量的木樁才能解鎖下一關，逐步累積進度，最終挑戰全部 16 個關卡。
遊戲全程使用 Canvas 繪製介面，畫面自適應各種螢幕尺寸，無論手機直橫屏或電腦瀏覽器都能流暢遊玩，並支援音效開關。失敗時可以觀看一段獎勵廣告繼續挑戰（落水可原地復活、超時可獲得額外時間），讓遊戲體驗更加友善。無論是想消磨片刻時光，還是想挑戰自己的反應與節奏感，《青蛙跳》都是一款值得收藏的休閒小遊戲。

Frog Jump is an HTML5 casual game built around the classic "hop across the river" gameplay loop. Set across three vivid scenes — a tropical jungle, a sun-baked desert, and a starry night river — the game combines smooth Canvas animation with playful sound effects for a satisfying, easy-to-pick-up experience.
Controls couldn't be simpler: press and hold anywhere on the screen to charge your frog's jump — the longer you hold, the farther it leaps — then release to launch. Land safely on the next log to keep moving forward; miss it and splash into the water, and the level ends. The game features 16 distinct levels that grow progressively harder: logs get shorter, sit at more varied heights, and drift farther apart, demanding sharper timing and judgment with every stage. Each level has a 30-second time limit and a jump target to hit — clear enough logs in time to unlock the next level and work your way toward conquering all 16.
The entire interface is rendered on Canvas and scales smoothly to any screen size, so it plays great on phones in portrait or landscape and in desktop browsers alike, with a toggle for sound. If you fall in the water or run out of time, you can watch a short rewarded ad to keep going — respawning right where you left off, or grabbing a few bonus seconds — keeping the experience friendly even when a jump goes wrong. Whether you've got a spare minute or want to master every level, Frog Jump is a pick-up-and-play casual game worth coming back to.
