Rarity & Drops
ChessVS cards come in four rarities, and every pack you open uses provably fair randomness — the drop rates are fixed in code and publicly verifiable. No one, including ChessVS, can rig a pack.
The four rarities
| Rarity | Look | Durability | Season-end behaviour |
|---|---|---|---|
| Common | Base club artwork | 8 games | Fully consumed |
| Rare | Enhanced finish | 14 games | Fully consumed |
| Epic | Premium treatment | 20 games | 50% of remaining uses carry over |
| Omega | Animated, holographic | 30 games | 100% carries over |
The ability on a card is the same across all four rarities — rarity changes durability, combat stats, visual treatment, and season-end longevity, not what the card does.
Standard pack drop rates
| Rarity | Chance |
|---|---|
| Common | ~55.6% |
| Rare | ~28.3% |
| Epic | ~15.2% |
| Omega | ~1.0% |
These rates are fixed in the contract and identical for everyone.
The pity system
So a long unlucky streak never ruins your experience, ChessVS tracks a pity counter:
| If you open... | ...this happens |
|---|---|
| 8 packs with no Epic | Your 8th pack guarantees an Epic |
| 50 packs with no Omega | Your 50th pack guarantees an Omega |
Each counter resets after it triggers. You can check your own pity counts at any time.
Premium boxes
| Box | Cost | Guarantees |
|---|---|---|
| Battle Box | 500 FOCUS | At least 1 Rare |
| Legendary Box | 500 CVS | At least 1 Epic |
| Omega Vault | 2,000 CVS | 1 Omega from a curated pool + an exclusive board skin |
Club packs
During a season, Club Packs boost the drop rate for that season's spotlight club. The exact boost is published with each Club Pack release. All other mechanics — pity, base rates — stay the same.
Provably fair
Every pack opening is recorded as an on-chain transaction. The random seed and the resulting cards are permanently verifiable. There is no hidden, off-chain randomness — the system cannot quietly change your odds.
