◆Case Split

Built for TCG case openings

Split a case cost by what each person wants

Enter the case price, tag every card by rarity, assign it to a friend, and get a fair per-person cost weighted by rarity — not just card count.

Weighted by rarity

Secret Rares cost more than commons. Default weights: Super 1.0, Ultra 1.5, Secret 1.7, Rare 0.5.

Assign per card

Every card goes to a participant. Unclaimed cards don't affect anyone's share.

How Case Split works

Splitting a sealed case of a trading card game with friends sounds fun until it comes time to settle up. Splitting evenly by card count is easy, but it isn't fair — one person walks away with the chase secret rare and another gets a stack of bulk. Case Split fixes that with a simple weighted math model everyone agrees to before a single pack is opened.

You set the case cost, list each rarity in the set and its weight (a Mythic is worth more than a common), add every participant, and assign each card as you open it. The app keeps a running total of what each person owes based on the rarities of the cards they claimed.

Cards with a well-known market price (an Alt Art, a Serialized pull, a $50 chase) can be entered as a fixed cost instead of a weight. Fixed costs come out of the case cost first, then the remainder is split by weights. No spreadsheet, no arguments.

Four steps

  1. 1Create the case. Pick the game and confirm the rarity weights.
  2. 2Invite the group. Add participants — accounts or guests. Share the invite link.
  3. 3Open & claim. Log each card and assign it to whoever's keeping it.
  4. 4Settle up. The Split panel shows each person's total in real time.
