## What is Dice 21?

Place a die. Make exactly 21. Clear the line.
Dice 21 is a quick number puzzle about choosing an open cell while reading the next roll. The rule is simple; the decisions and chains keep growing.

HOW TO PLAY
• Place the NEXT die in any open cell.
• Make one row or column total exactly 21 to clear it.
• Clear a row and column together for a DOUBLE 21 and 8× the points.
• Clear again within two moves to build a CHAIN worth up to 25×.
• Spend a Flip Token to turn one die to its opposite face.
• In timed modes, each score target adds 15 seconds.

PLAY YOUR WAY
• Four modes: 90 seconds, 3 minutes, 5 minutes, and Endless
• A high score for every mode, plus Game Center leaderboards
• The same daily dice sequence for every player
• Play streaks and rotating weekly missions
• Share your score and maximum CHAIN as an image
• 13 animal worlds, including rabbit, bear, cat, penguin, and more

## Version history (last 5 releases)

### 1.0.4 — 2026-08-14

Restored one continue in every eligible standard game and clarified Daily practice replays. Removed distracting board tap highlights, added clearer remaining totals, improved Flip controls, How to Play, weekly missions, and results, and added shareable result cards and mission reward feedback.

### 1.0.3 — 2026-08-12

All 13 themes are now animal worlds. Each theme’s character reacts to hints, 21 clears, and time pressure. We also refined the board, next-die area, and start screen, while reducing continuous animation to improve energy use.

### 1.0.2 — 2026-08-04

Added a hands-on place-3, make-21 tutorial, result sharing, a fair same-dice Daily Challenge, a clear Next Target after each run, and a new Crafted-theme icon. CASCADE now replaces CHAIN with a stronger ×6, ×10, ×14… scoring curve up to ×50.

### 1.0.1 — 2026-07-29

Fixed rewarded continues, strengthened paid ad skipping, and ensured post-game ads follow Play Again or Change Time exactly as selected.

### 1.0 — 2026-07-26

No release notes.
