Enhanced Wargames
Hello, Dreamhack users!
The Dreamhack Wargame system has been reborn as a data-driven learning platform, centering on a refined tier system to support your growth more effectively. Explore the new features and design your own security learning roadmap!
Difficulty System
The New Tier System
The previous 1-10 difficulty scale has been replaced by a global standard tier-based system.
- New Tiers: Beginner → Bronze(4→1) → Silver(4→1) → Gold(4→1) → Platinum(4→1) → Diamond(4→1) → Master(4→1)
- Standard Challenges: These are reference challenges selected by the Dreamhack team to define each tier.
- Blind Mode: You can now toggle the visibility of a challenge's difficulty.([Account] > [Publicity] > [Wargame Settings])
| Blind | ![]() |
Shown on challenges when Blind Mode is enabled. |
Difficulty Spectrum by Path
Check how our existing Paths align with the new difficulty system. The start and end points of each bar represent the minimum and maximum tiers covered by that Path.

Exceptions
Some challenges cannot be rated due to various reasons.
| Unrated | ![]() |
Displayed for challenges with a pending difficulty rating. |
| Graveyard | ![]() |
Displayed for challenges excluded from the rating system due to limited educational value or insufficient discriminative power. |
Difficulty Voting
Please review the Wargame Vote Guide before casting your difficulty vote.
Setting the Standard Together
Difficulty is no longer a simple average. A weighted algorithm is applied to improve system reliability.
- Skill-based Weighting: Votes that deviate significantly from your own Class level will have less impact. In other words, evaluations from experienced users in the relevant field are reflected with greater weight.
- Time Recency: A half-life mechanism is applied so that older votes carry less weight, while recent votes — reflecting current security trends and user perspectives — are weighted more heavily
- Growth-based Re-voting: As your skills grow, do past challenges feel different? Re-vote anytime to keep Dreamhack's difficulty data accurate.
- Reliability Index (Standard Error): The system calculates the Standard Error (SE) of votes. Challenges with an SE below 0.5 reach a 'Very Stable' status.
Wargame Scoring
Our scoring system has been refined to more fairly validate your expertise. We have moved beyond simple accumulation to a weighted system that prioritizes your peak performances.
Scoring Policy
Base points are determined by difficulty. While your score builds as you solve more, it is primarily driven by your top performances.
- Overall Score: All challenges solved by the user (regardless of field) are ranked by score for calculation.
- Strategic Growth: To maximize your score, focus on pushing your boundaries by solving high-tier challenges rather than accumulating low-tier solves.
| Category | Weight | Logic |
|---|---|---|
| Top 60 (1st~60th) | 100% | Top 60 overall solves. |
| Next 120 (61st~180th) | 30% | Next 120 highest-scoring solves. |
| Bottom 240 (181st~420th) | 10% | Next 240 highest-scoring solves. |
- Topic-based Score: Scores are calculated by ranking challenges within a specific field (Pwn, Rev, Web, or Crypto).
- Strategic Growth: For a top-tier global ranking, it is advantageous to achieve high-tier solves (at least 30 total) across diverse fields.
| Category | Weight | Logic |
|---|---|---|
| Top 30 (1st~30th) | 100% | Top 30 highest-scoring solves per field (Pwn, Rev, Web, Crypto). |
| Next 60 (31st~90th) | 30% | Next 60 highest-scoring solves per field. |
| Bottom 120 (91st~210th) | 10% | Next 120 highest-scoring solves per field. |
Class & Keyword
Class: Learning Track
- Skill Verification: Each Class (C1–C7) consists of 8–13 curated challenges.
- Rewards: Unlock exclusive graphic assets upon completing each stage.
- Prerequisites: Higher Class certifications require the completion of some preceding Classes.

Wargame Keywords: Organic Connections
Wargame Keywords are available for Starter plan users and above. Explore more detailed paths through 'Learn by Category' in Wargames.
- Tech Tags: Challenges are categorized using hierarchical keywords such as Pwnable – Exploit Tech – Tcache Dup.
- Smart Recommendations: If you get stuck, we’ll suggest lower-tier challenges or related Units with the same keyword to help you keep moving forward without losing momentum.
