Rarity is the single most important property of a Kickchain card. It determines how your card looks, how much it’s worth on the leaderboard, and how rare it truly is in the broader collection. Every rarity tier is earned — not random — and it’s locked in the instant your prediction hits the blockchain.

​
How rarity is determined

When you submit a prediction, Kickchain reads the current decimal odds for the outcome you chose and assigns a rarity tier immediately. That tier is written into your prediction’s on-chain account alongside the odds themselves, and it never changes — even if the odds shift dramatically after you predict. The logic is straightforward: the longer the odds, the rarer the card. Backing a heavy favourite at odds below 2.00 gives you a Common. Calling a genuine underdog at 7.00 or higher earns you a Legendary.
Odds are stored on-chain as decimal odds multiplied by 1,000 (for example, odds of 3.50 are stored as 3500). This integer format preserves precision without floating-point rounding. The rarity thresholds in the table below show both representations.

Visual treatment by rarity

Each tier has a distinct look that makes it immediately recognisable in your collection and when you share cards.

Common

Accent colour: Steel #9aa6bdNo foil treatment. Clean, flat card art with a steel-toned frame. These are your workhorse predictions — the likely outcomes that form the backbone of any complete album.

Rare

Accent colour: Blue #5b9bffFeatures a streak diagonal foil that catches the light with subtle lines across the card face. Rare cards represent genuine contest predictions where the outcome is genuinely in question.

Epic

Accent colour: Purple #a78bffFull holographic foil treatment with a shifting shimmer across the entire card face. Epic cards are for calling real long shots — outcomes most fans wouldn’t dare predict.

Legendary

Accent colour: Gold #f2c14eHolographic foil with gold accents throughout the frame, spine, and badge. Legendary cards are the rarest in the game, reserved for bold calls on genuine underdogs at 7.00 or greater.

Why rarity matters

Rarity affects your Kickchain experience in three distinct ways: 1. Leaderboard scoring Only winning predictions score points, but not all wins are equal. Your score is the sum of rarity weights for each correct prediction. A Legendary win is worth five times a Common win. If you go through a tournament backing only clear favourites, even a perfect record scores far fewer points than a player who correctly calls a few high-odds upsets. 2. Visual prestige Holographic and streak foil effects are exclusive to Rare, Epic, and Legendary cards. Your collection page shows all your cards, and rarer cards stand out immediately — both to you and to anyone you share them with. 3. Collectibility Because Legendary cards require odds of 7.00 or higher at the moment of prediction, they are structurally scarce. Far fewer matches will have an outcome at those odds, and the window for predicting them at that rarity can close as odds shift. This natural scarcity makes Legendary cards the most sought-after in any WC26 album.
To chase Legendary cards, look for heavy underdogs — a minnow nation facing a tournament favourite, or an “Under” market when both teams are prolific scorers. Keep an eye on team news too: a late injury to a key player can push a team’s odds past 7.00 shortly before kick-off, briefly opening a Legendary prediction window.

Rarity is permanent

Once your prediction is on-chain, the rarity tier is sealed. There’s no upgrading, rerolling, or changing it after the fact. The odds-at-pick value and rarity are fully verifiable on-chain — you (and anyone else) can confirm exactly what odds you predicted at and why your card earned the tier it did.
