Practical use
How to plan without official odds
- Record how many unique letters you own.
- Open a sample of packs and estimate how often one adds a new letter.
- Measure your pack-opening pace, then enter both observations in the completion planner.
- Recalculate after a Luck or Pack Speed upgrade changes what you observe.
Avoid bad assumptions
Three claims this page does not make
- It does not assign percentages to Common or Mythic packs.
- It does not rank individual letters without their effects and board values.
- It does not state how Symbol Packs unlock before a public source shows the requirement.
FAQ
Pack and rarity questions
Which rarity endpoints are public?
Only the stated endpoints, Common and Mythic, are confirmed publicly. This page does not invent the tiers between them.
Are the letter pack odds official?
No official numeric odds were found. Use the calculator only with a rate you enter from your own observations.
Do Symbol Packs exist?
Yes. Their existence is stated by the creator, but their unlock requirement and contents are not publicly detailed.
Are Mythic letters always the best to mount?
There is not enough public letter-level income data to make that claim. Compare what your in-game board shows.
