Drop Merge: Number Chain

Drop falling jewel groups onto a board, rotate them, line up same-number tiles, and merge them into bigger ones. Each chain doubles your score, and pulling off a 5+ chain fires a fullscreen explosion across the playfield. A hybrid drop-merge puzzle built around the catharsis of nailing a huge chain combo.

[Features]

■ Chain combos take center stage
Score multipliers grow with each link in a chain — 1x, 2x, 4x, 8x, and 16x at 5+ chains. Big chains shake the screen and unleash a fullscreen fireworks burst. The moment your planned chain detonates is pure satisfaction. After a 5+ chain the next piece holds for a beat so you can savor the explosion.

■ Multi-jewel falling pieces (1–4)
2-jewel pairs, 3-jewel I and L trominoes, and seven different 4-jewel tetromino shapes — every drop is a fresh shape-and-rotation puzzle. Set your max simultaneous count (1–4) in Custom Rules.

■ Fluid controls
Slide left/right while falling to choose your column. Tap to rotate 90° clockwise. Quick down-swipe = hard drop. Hold a downward drag = soft drop. Move at your own tempo.

■ Existing-jewel priority merge
When a multi-jewel piece lands with a same-value match next to a tile already on the board, that existing tile wins the merge — your planned chains land exactly the way you imagined.

■ Per-jewel split landing
When a multi-jewel piece lands across uneven columns, each jewel falls independently to its own resting cell — opening up shape-aware play.

■ 11 customizable rules
Column count (4–8), simultaneous jewel max (1–4), Timer mode, Wild jewels, Preview count, Danger bonus, Auto-clear, Initial tile placement, and more. Mix and match — practice mode to hardcore, the difficulty is yours.

■ Wild jewels
Every 10th jewel is a Wild that bonds with any number. Clutch your way out of tight boards or seed a massive chain.

■ Danger zone
While the top 2 rows are stacked, every merge gets a 2x multiplier. Every move walks the tightrope between risk and reward.

■ 1024+ auto-clear
Merging into 1024 or higher automatically clears the lowest tile on the board. Disable it with the "No auto-clear" rule if you prefer.

■ Pause support
Tap the top-left pause button to freeze the game any time. Swap apps, get a notification, or pull down Control Center and the game auto-pauses. Resume right where you left off.

■ Seed replay
Past runs are saved with their fixed seed. Replay the same tile sequence and try again. "Same luck, better choices" — measure your skill against your past self.

■ 15 languages
Japanese, English, Simplified Chinese, Korean, French, German, Spanish, Brazilian Portuguese, Russian, Arabic, Hindi, Bengali, Urdu, Turkish, Indonesian.

■ Game Center leaderboards
Compete worldwide on three boards: all-time best score, daily best, and longest chain. Sign in to Game Center to play (offline play is not supported). Local scores and run history also live on your device, included in your iCloud backup.
