Lucky Coin

Lucky Coin is a game of chance where players reveal hidden rewards on a 3×3 board.
The primary reason to play Lucky Coin is the opportunity to obtain Rare Seals, one of the rarest rewards currently available in War of Continents.
Lucky Coin is currently the only confirmed source of Rare Seals.
How It Works
Each Lucky Coin board contains 9 hidden cells.
To reveal a reward, a player must spend Lucky Coins and open a cell.
Every opened cell immediately reveals its reward.
Each completed board awards exactly one Grand Prize. It can be revealed before the final cell, but opening all 9 cells guarantees it.
The position of a cell does not determine its reward.
Opening Costs
Each newly opened cell costs twice as much as the previous one.
| Cell | Cost |
|---|---|
| 1 | 1 |
| 2 | 2 |
| 3 | 4 |
| 4 | 8 |
| 5 | 16 |
| 6 | 32 |
| 7 | 64 |
| 8 | 128 |
| 9 | 256 |
Opening all 9 cells costs a total of 511 Lucky Coins.
Hero XP Scroll Rewards
Every reveal that is not the Grand Prize awards Hero XP Scrolls. The standard reward increases through the board's eight ordinary reward levels:
| Reward Level | Reward | Hero XP after redemption |
|---|---|---|
| 1 | 1 Common Hero XP Scroll | 50 |
| 2 | 2 Common Hero XP Scrolls | 100 |
| 3 | 3 Common Hero XP Scrolls | 150 |
| 4 | 4 Common Hero XP Scrolls | 200 |
| 5 | 1 Uncommon Hero XP Scroll | 150 |
| 6 | 2 Uncommon Hero XP Scrolls | 300 |
| 7 | 3 Uncommon Hero XP Scrolls | 450 |
| 8 | 5 Uncommon Hero XP Scrolls | 750 |
If the Rare Seal is revealed early, later cells continue with the remaining standard reward levels. A fully opened board awards all eight standard rewards exactly once: 10 Common and 11 Uncommon Hero XP Scrolls, worth 2,150 Hero XP after redemption.
Rare Seals
Every Lucky Coin board can award exactly one Grand Prize.
The Grand Prize is always a Rare Seal.
Rare Seals are among the most valuable items available during the First Epoch and provide the highest level of elemental containment currently available in the game.
Once the Grand Prize has been revealed, the remaining cells award the remaining standard Hero XP Scroll rewards. Players who reveal all 9 cells are guaranteed to obtain the Rare Seal.
Fully clearing a board guarantees that the Rare Seal will be found.
Resetting The Board
Players may stop at any time.
If continuing the current board is no longer worth pursuing, it can be abandoned and a new one started.
This allows players to decide whether to continue searching for the Rare Seal or begin a fresh board.
Progress on the current board is lost when a new board is started.
Strategy Tips
- Opening only a few cells minimizes risk.
- Opening more cells increases the chance of finding the Rare Seal.
- Fully clearing a board guarantees that the Rare Seal will be found.
- A cell's position does not change its cost or reward.
- Consider your available Lucky Coins before committing to a full board.
- Remember that each new cell costs twice as much as the previous one.
