A number-first battler for ages 8+. Two players, a deck of ten, first to four captures. Every card carries three things: ⚔ ATK (1–5), ❤ HP (2–10), and a +N ▶ combat box — it hits +N harder when the defender wears any listed element (either of its two badges counts).
Commit a deck of exactly 10 cards — at most 2 copies of the same card.
Seven of your ten are dealt face-up — both players see both sevens. Three stay hidden.
Secretly switch up to 3 of your shown 7 with your hidden 3. They know 7 of your 10 — never your final line.
Arrange your final 7 face-down in flip order and place the pile on the table.
Flip top card vs top card. Element advantage adds +N ⚔. A card falls if the attacker's effective ⚔ ≥ its ❤ — checked both ways at once. A fallen card is captured; both fall = mutual KO, nobody scores.
First to 4 captures. (All-in, agreed up front: no early stop — all 7 flips play out, most captures wins. Tie: sudden death from the bench.)
Friendly (the default): nothing changes hands — play for bragging rights, forever, free. Keeps (both agree before the first flip): the winner takes the cards they captured. Your deck churns every match — deck construction is the real skill. One rule sits above everything:
The server deals every vs-AI matchup and remembers your open match. Refresh after seeing the rival's cards? The same matchup comes back. An honest disconnect loses nothing; fishing for an easy rival gains nothing.
| Coming back later | A resume prompt greets you: an unfinished match continues where it stands; a finished one replays in full before you can queue again. One match at a time. |
|---|---|
| Waiting on a rival | Their remaining clock shows on your screen — waiting always has a visible ceiling. |
| While you're away | Time never pauses. If your side was auto-arranged and lost a Keeps match, those captured cards did move — and the full replay shows exactly how. Win them back. |
No player's call ever moves a card in that player's favor. vs the AI, rivals occasionally miscall by accident, in their own favor — catch it and the truth stands; the only card a call can ever move is the one you lose by agreeing to a bad call. In PvP, calls are score-kept for accuracy only: cards always move by engine truth. Calling "I win" every flip wins nothing — it just embarrasses your accuracy stat.
Holdoria is the 3D board game played with the same cards. It has two modes. HODL (Friendly): nothing changes hands. That is the only mode you can play today. Burn is not live yet; its odds are published here first so nobody meets them for the first time at the table.

* Zedakazm, Vernirox and Quadrossal never hatch from an egg. They come from packs only. A mythic egg is one of the other seven mythics, each equally likely. Within every other rarity each card is equally likely.
The burn is just as real, but the egg is capped by the lowest rarity among the three cards you staked, and never above Rare. Eggs are given only for a win, one for each rival pet defeated.
| Lowest card staked | Rare | Uncommon | Common |

Burn is a sink by design: across everyone who plays it, fewer and lesser cards come out than go in. These odds are proposed and will be final here before Burn opens; any later change is dated in the rule history below.
✅ Re-rolling a matchup after seeing the rival's cards — impossible, in PvP and vs AI.
✅ Faking a rival deck or result at settle — the server replays its own record.
✅ NPC stand-in wins inflating the PvP leaderboard — excluded and labeled.
✅ Losing cards because you disconnected — the match waits or the Keeper plays your side fairly; your collection re-syncs on any page load, and the full replay waits for you.
✅ A capture settling twice — every match settles exactly once, server-side, from the same deterministic engine you watched.
Rules change carefully and in the open. Every change bumps the version number in the header and moves the superseded wording here, dated — old rules stay findable forever.
Initial public ruleset: the six-step game · Keeps opt-in before the match · dealt-is-final (server-pinned vs-AI matchups, no re-rolls) · PvP arrange clock 90s-from-first-sight with 10-minute never-opened cap · NPC Keeper offered at 90s, never forced, never counted on the PvP board · one PvP match at a time with resume · stand/fall calls judged by the engine, no forfeit rule.
