Sumdle

New daily seed at midnight JST. One board, played worldwide. Drop, merge, beat yesterday. Replay the same seed in Shadow Replay. No login, no friends list, no nonsense.

Sumdle is a daily merge puzzle. One new board opens each day at midnight JST, identical for every player worldwide.

One drop a day. Beat yesterday.

Drop numbered tiles, merge matching values, and keep the stack below the danger line. The goal is simple: score higher and build larger tiles before the board fills up. When the board is full, your official daily run ends.

Your first run counts as the daily official score. After that, Shadow Replay lets you practice the same seed, compare against your official result, and chase a cleaner line. Shadow Replay is granted via a rewarded ad — once per day, free.

Features:

• One official daily puzzle (resets at midnight JST)
• Physics-based tile drops and merges
• Combo, chain, milestone, and danger feedback
• Shadow Replay for same-seed practice (free, 1/day via rewarded ad)
• Personal bests, recent results, streaks, and replay bests
• Shareable 4x4 result card in a wagashi (Japanese confection) color palette
• Free, ad-supported first release
• No login, no friends list, no signup

Designed to be readable, fast, and repeatable: one board, one score, one more run.
