TZOKER Glossary

The single number drawn from the 1–20 Tzoker pool, separately from the five main numbers. Required for the jackpot and for the bonus tiers (5+1, 4+1, 3+1, 2+1, 1+1, 0+1).

A number that has been drawn fewer times than the average over the selected timeframe. Cold numbers are a historical statistic — they do not become more (or less) likely to be drawn next.

One playable combination of 5 main numbers plus 1 Tzoker. The minimum priced unit on a TZOKER ticket. Cost: €0.50 per column. Minimum playable ticket is 2 columns (€1.00).

A betting structure that picks more than 5 main numbers and/or more than 1 Tzoker, generating every possible 5+1 combination. Cost = C(main, 5) × tzoker_count × €0.50.

The official OPAP event where the winning 5 main numbers and the Tzoker are randomly selected. TZOKER draws happen Tuesday, Thursday and Sunday at 22:00 Athens time.

OPAP's incrementing identifier for each TZOKER draw. Used internally by tzoker.app to link draw results to their statistics and prize-tier breakdowns.

The average payout per €1 staked over an infinite number of plays. For TZOKER it is well below €1 — the game's prize pool is set by regulation as a fixed percentage of sales (the rest funds operator profit, taxes and good causes).

A prize tier that pays a constant amount regardless of how many winners share it. In TZOKER the only fixed prize is tier 9 (0 main + 1 Tzoker), which pays €1.00 per winning column.

The number of times a specific main number (1–45) or Tzoker (1–20) has been drawn in a given timeframe (1 month, 3 months, 1 year, 5 years, all-time, etc.).

The mistaken belief that past random outcomes affect future ones — for example, that a number which hasn't appeared recently is 'due'. Each TZOKER draw is independent; previous results carry no information about the next one.

A number that has been drawn more times than the average over the selected timeframe. Like cold numbers, hotness is descriptive of past data and has no predictive power on a fair lottery.

The probability distribution that describes the chance of drawing exactly k matches from a fixed pool without replacement. TZOKER odds are computed as P(k main matches) × P(Tzoker match or not) — see the Odds Explained guide.

The top prize, awarded for matching all 5 main numbers and the Tzoker. The TZOKER jackpot is a guaranteed minimum of €1,000,000 and rolls over until won. Odds: 1 in 24,435,180 per column.

The pool of integers 1 to 45 from which 5 winning numbers are drawn at each TZOKER draw, separately from the Tzoker number.

The smallest jackpot OPAP guarantees for the next TZOKER draw, currently €1,000,000. If the previous draw's pool exceeds this, the larger amount is published instead.

The likelihood of an event, usually expressed as 'X in Y' (e.g. 1 in 24,435,180 for the TZOKER jackpot). Odds describe the chance per single column played, not per ticket.

OPAP S.A. — Greece's regulated lottery and sports-betting operator. Holds the exclusive licence to organise TZOKER, JOKER, LOTTO, KINO, PROTO and other games in Greece and Cyprus.

A payout method where the prize pool of a tier is split equally between all winners of that tier. In TZOKER, tiers 1–8 are pari-mutuel; only tier 9 is fixed.

The total amount returned to players from each TZOKER draw, set by regulation as a fixed percentage of total sales for that draw. The pool is then split across the 9 prize tiers by formula.

One of the 9 winning combinations in TZOKER, ranging from tier 1 (5 + 1 Tzoker, jackpot) to tier 9 (0 + 1 Tzoker, fixed €1.00). Each tier has its own probability and payout type.

An automatically generated random ticket. On tzoker.app, the Quick Pick button uses a uniform random algorithm that picks 5 main numbers from 1–45 and 1 Tzoker from 1–20.

When a TZOKER draw produces no jackpot winner, the unwon pool is added to the next draw's jackpot. Multiple consecutive rollovers can grow the jackpot to tens of millions of euros.

A group of players who pool money to buy more columns than each could alone. Syndicates do not change the per-column odds, but they raise the chance the group will win at least something — at the cost of splitting any prize.

The physical or online receipt for one or more TZOKER columns. A single ticket can contain a simple play (one column), several columns, or a wheel system.

The 5/45 + 1/20 lottery game operated by OPAP. Players pick 5 main numbers from 1–45 and 1 Tzoker from 1–20. Draws: Tuesday, Thursday, Sunday at 22:00 Athens time.

An optional add-on offered occasionally by OPAP that multiplies non-jackpot prizes by a random multiplier announced at draw time. Not available on every draw.

The total number of columns played across all TZOKER tickets for a single draw. Reported by OPAP and used on tzoker.app to track participation trends per draw.

The total number of distinct TZOKER tickets sold for a single draw. A single ticket can hold many columns, so wager_tickets is always lower than wager_columns.

The 5 main numbers (1–45) plus the Tzoker (1–20) drawn by OPAP at the official draw. These are the canonical numbers used to evaluate every ticket for that draw.

Greek lottery tax deducted from prizes before payout. Brackets: 0% up to €100, 2.5% €100–€500, 5% €500–€2,500, 7.5% €2,500–€1,000,000, 10% above €1,000,000. Calculated per prize tier independently.
