Prison: mine ranks and prestige

Unlock mines A–J in order. Open /guide → Mine Ranks, or /gui ranks, to review your next purchase. Rank A is your starting mine.

Current rank prices
• B: 4,000 Gems
• C: 12,000 Gems
• D: 32,000 Gems
• E: 80,000 Gems
• F: 180,000 Gems
• G: 400,000 Gems
• H: 900,000 Gems
• I: 2,000,000 Gems
• J: 5,000,000 Gems

These are individual upgrade prices: A through J costs 8,608,000 Gems in total. Unlocking a rank gives access to that mine; it does not automatically buy a pickaxe.

Optional prestige after J
Open /guide → Prestige or /prestige, review the charge, then confirm. The first prestige costs 2,000,000 Gems; later prestige prices increase by 2,000,000 per level, through 100 levels.

Prestige restarts your mine rank at A. Keep tools, backpack contents and unlocked storage rows, and Gems left after the charge. Unlock later mines again. This is separate from restarting one Survival skill.
