Game Basics
In Dragonsweeper, you control a character navigating a grid filled with hidden monsters of various power levels:
- Starting Stats: You begin with 5 HP (health points)
- Monsters: Each monster has a level number that determines:
- How much damage they deal to you when clicked
- How much gold they drop when defeated
- Leveling System:
- Collect gold to level up
- Each level-up fully heals you and adds +1 to your maximum HP
- Gold required increases by 3 for each subsequent level
- Goal: Reach level 15 and defeat the dragon to win
The game follows a Minesweeper-like format where numbers indicate the total level of monsters in the 8 surrounding tiles. However, when a number exceeds 99, the first digit represents mines and the last two digits represent monster levels.
Key Items & Resources
Health Resources
- Heart Scrolls: Fully restore your HP (7 on the board)
- Level-ups: Each level-up restores your health to full
- Treasure Chests: May contain heart scrolls (2 chests contain hearts)
Gold/XP Sources
- Regular Monsters: Drop gold equal to their level
- Treasure Chests: Two contain 5 gold each
- Deactivated Mines: Worth 2 gold each (18 gold total)
- Gnome: Provides 10 gold when finally caught
- Walls: Provide random gold amounts (varying efficiency)
Monster Guide
Understanding monster patterns is the key to success. Here's what to look for:

The Monsternomicon book showing all monster types and information
Common Monsters
Monster | Level | Description | Strategy |
---|---|---|---|
Rat | 1 | Always faces toward the Rat King's column | Great for early gold |
Bat | 2 | No special pattern | Good low-risk target |
Gargoyle | 4 | Always appear in pairs (horizontal/vertical) | Eyes indicate partner's direction |
Green Slime | 5 | No special pattern | Can be revealed by scroll |
Purple Slime | 8 | Surrounds the Slime Warlock | Only on outer rows/columns |
Mimic | 10+ | Appears as a treasure chest | Avoid until stronger |
Mine | 100 | Can be deactivated | Worth 2 gold after deactivation |
Special Monsters
Monster | Level | Location | Special Ability |
---|---|---|---|
Gnome | 0 | Teleports to empty spaces | Gives 10 gold when cornered |
Slime Warlock | 1 | Always on an edge (not corner) | Scroll reveals all slimes |
Rat King | 5 | Anywhere | Scroll reveals all rats |
Gazer | 5 | Anywhere | Creates "?" marks in diamond pattern |
Lich | 11 | Always in a corner | Scroll deactivates all mines |
Dragon | 15 | Center of the board | Final boss |
Visual Clues to Watch For
- Question Marks (?): Indicate a Gazer is within 2 squares
- Rats Standing Upright: In the same column as the Rat King
- Rats Facing Left/Right: Rat King is in that direction
- Clusters of 8s: Indicate the Slime Warlock is nearby
- High Numbers in Corner: Likely the Lich (always level 11)
Quick Navigation
Step-by-Step Strategy
Starting Out (Levels 1-5)
- Begin Safely: Click the two orbs to reveal initial safe areas
- Early Exploration:
- Prioritize finding low-level monsters (rats, bats)
- Look for patterns that reveal monster positions
- Use right-click to mark suspected monsters
- Find Key Characters Early:
- Locate and defeat the Rat King to reveal all rats
- Find the Slime Warlock to reveal all slimes
Mid-Game (Levels 6-10)
- Resource Management:
- Use HP efficiently - try to reach exactly 0 HP before leveling up
- Save heart scrolls for higher levels when possible
- Mark high-level monsters instead of fighting them immediately
- Strategic Exploration:
- Focus on revealing empty spaces to eventually catch the gnome
- Work toward corners to find the Lich
- Eliminate Gazers to remove "?" tiles
End-Game (Levels 11-15)
- After Finding the Lich:
- Kill it immediately when you reach 11 HP
- Collect all deactivated mines (18 free gold)
- Final Cleanup:
- Use remaining heart scrolls at higher levels for maximum benefit
- Kill remaining monsters in order from lowest to highest level
- Leave the dragon for last to achieve a perfect score
Pro Tips for a Perfect 365 Score
Heart Scroll Efficiency
- A heart scroll at level 5 restores 5 HP
- A heart scroll at level 15 restores 15 HP

The Golden Rules
- Information > Gold: Prioritize revealing new tiles over killing known monsters
- Always fight the Lich at exactly 11 HP

Common Mistakes to Avoid
- Using heart scrolls when you still have HP left
- Killing high-level monsters too early
- Not marking suspected monster locations
- Ignoring pattern clues like rat directions
- Forgetting to check corners for the Lich
- Neglecting to use walls strategically
Understanding the Death Screen
One of the game's unique hints is found in the Monsternomicon (monster book):
"Observing patterns when dead is also useful for subsequent games"
After dying, take time to study the revealed board. Note monster placements, patterns, and think about what you could have done differently. This "post-mortem" analysis is crucial for improving your gameplay.
