A Yu-Gi-Oh! card scanner that gets the printing right

Yu-Gi-Oh! reprints the same card across rarity tiers, sometimes within a single set. The name and text are identical. The foiling, the print run, and the price are not.

• Common and Rare: no foil, or a silver foil name.
• Super Rare: holofoil artwork with a plain name.
• Ultra Rare: holofoil artwork with a gold foil name.
• Secret Rare: speckled holofoil artwork and a rainbow-etched name.
• Ultimate Rare: embossed relief foil across the artwork and borders.
• Ghost Rare: pale, shifting holographic artwork.
• Quarter Century Secret Rare: the 25th-anniversary treatment, with foiling across the whole card and a Quarter Century stamp.

On the same card, the gap between tiers can be the difference between bulk and a binder centerpiece. A tracker that records only the card name is recording the wrong number. Cube logs the printing you actually own and values it as that printing.

Every modern Yu-Gi-Oh! card carries a code like LOB-EN001: a set prefix, a region code, and a card number. Combined with rarity, that code pins the card to one exact printing. This matters because Yu-Gi-Oh! reprints aggressively. A tournament staple like Ash Blossom & Joyous Spring has been reprinted at multiple rarities across several sets, and the code is how you tell one printing from another. Each printing has its own rarity spread and its own price.

Cube reads the card in front of the camera and cross-checks each scan multiple ways before committing to a match. The goal is the right printing, not the closest name. When a scan resolves, you see the set, the card number, the rarity, and the price attached to that specific printing. If the market values your copy differently from the cheapest version of the same name, your collection total reflects that.

Cube's Yu-Gi-Oh! card data comes from YGOPRODeck, which covers cards at the printing level: sets, card numbers, and rarities, not just names. Prices come from live trading-card market data and refresh continuously, so the number on your screen tracks the market rather than a snapshot from last month.

Each game gets a source built for it: Scryfall for Magic: The Gathering, TCGdex for Pokemon, Lorcast for Lorcana, YGOPRODeck for Yu-Gi-Oh!. One app, four games, no manual data entry.

Continuous scanning means no tap-confirm-tap-confirm loop. Open the scanner, move down the page, and Cube keeps identifying cards as they enter the frame. A full trade binder goes from cardboard to catalog in one sitting, and a deck box takes minutes. Cataloging a collection you have put off for years stops being a weekend project.

A Yu-Gi-Oh! collection is an asset with a price history, and Cube treats it that way. It tracks cost basis against current value, return over time, and set-completion progress. You can see whether the Secret Rare you bought near its peak has recovered, what your binder is worth today against what you paid for it, and which sets you are two cards away from finishing. If you have ever kept a spreadsheet for this, Cube is the spreadsheet that updates itself.

The free tier is 150 cards with full value tracking, continuous scanning, and the leaderboard. Pro is $9.99 a month or $49.99 a year: unlimited cards, per-card return, unlimited collections. No countdown timers, no invented discounts.

The leaderboard is opt-in and ranked by distinct-card value. Duplicates do not count, so forty copies of one Ultra Rare will not outrank a genuinely deep collection.
