Core Loop Step-by-Step
The full game is built around repeated sarcophagus attempts. Follow this sequence to build a reliable foundation before pushing for long relic streaks.
Begin a New Attempt
Review the current run state, objective, and displayed success chance before interacting with the coffin. Each attempt is part of a larger 12-relic collection plan, not an isolated click.
Open the Sarcophagus
Resolve the attempt. A success advances your consecutive collection sequence; a failure affects the current run's progress. Read the result screen carefully for newly revealed relic or event information.
Collect Scarabs and Upgrade
Successful openings reward Golden Scarabs. Spend them on success chance, opening speed, and reward multipliers before attempting longer streaks.
Plan the Next Attempt
Decide whether to keep pushing the current sequence or bank progress. Track which of the 12 relics you have already discovered so repeated finds don't mask missing slots.
Pursue Glyphs and Endings
Once the core loop is stable, use permanent glyphs and replayed decision points to unlock all 6 endings across runs.
An empty sarcophagus result can erase your current collection streak. Never treat any opening as risk-free, especially late in a long relic sequence.
Luck, Probability and Upgrades
Your base success chance starts at 25%. Understanding how consecutive probability works is essential to planning a full-game run.
| Attempts | Formula | Chance at 60% Success Rate |
|---|---|---|
| 1 | p | 60% |
| 2 | p² | 36% |
| 3 | p³ | 21.6% |
| 4 | p⁴ | 12.96% |
Because consecutive success multiplies against you, success-chance upgrades deliver the largest long-term value of any purchase in the game.
| Upgrade Category | Effect | Priority |
|---|---|---|
| Success Chance | Raises per-attempt probability | ★★★★★ |
| Opening Speed | Faster sarcophagus attempts | ★★★★ |
| Reward Multiplier | More Scarabs per success | ★★★ |
| Auto-Opening | Automates repeated attempts | ★★★ |
| Schrödinger's Cat Auto-Capture | Automates the cat event | ★★ |
Chance-First Build
- Maximize success probability early
- Best for long relic streaks
- Recommended for first full playthrough
Speed Build
- Prioritize opening speed
- Higher attempts per minute
- Pairs well with auto-opening later
Automation Build
- Invest in auto-open and auto-capture
- Best for idle progress and cleanup runs
- Strong in later playthroughs
If the same success rate applies across independent attempts, the chance of succeeding every time equals the rate multiplied across those attempts. The in-game result always remains the source of truth for each run.
All 12 Relics, 6 Glyphs and 6 Endings
The collection objective contains 12 relics tied to ancient deities, tracked as discovered versus undiscovered slots. Steam data confirms the full game also includes 6 glyphs providing permanent growth across playthroughs, and 6 distinct endings with branching conditions.
| Content Type | Count | Role in Full Game |
|---|---|---|
| Relics | 12 | Core collection goal; must be gathered consecutively |
| Glyphs | 6 | Permanent passive effects across runs |
| Endings | 6 | Branching outcomes based on choices and progress |
| Golden Scarabs | Currency | Fuels all upgrades |
Full Game Completion Checklist:
- Discover all 12 relics
- Unlock all 6 glyphs
- Trigger all 6 endings
- Unlock every Steam achievement
- Max out success chance upgrades
- Complete the resurrection of the mummy
Ending specifics vary based on your decisions and relic progress. Track each ending by its trigger conditions, and never assume one ending completes every ending-related objective. Check the Steam achievements page as the authoritative checklist.
Lore: The Real Unlucky Mummy Behind the Game
The game's title references British Museum object EA22542, a real collection record connected to the historical "Unlucky Mummy" nickname and its modern curse legends.
| Source Layer | What It Covers | How to Treat It |
|---|---|---|
| Museum record EA22542 | Cataloged object information | Factual reference (British Museum) |
| Historical nickname | Popular label and reputation | Not a formal ancient designation |
| Curse stories | Misfortune legends and retellings | Popular culture, not documentation |
| Game usage | Thematic foundation for the title | Fiction built on the real reference |
The documented provenance lives in the museum catalog, while supernatural misfortune stories belong to later retellings. Unlucky Mummy draws on the recognizable reference for atmosphere without claiming the fiction is museum history.
