Why should Ι choose a System Game?

Definitions
System Code:
The code of the system you have chosen, which you need to mark on the slip.
Numbers Selected:
The numbers which you need to mark on the slip.
Total Columns:
The number of columns (of 5s) generated by the system for the draw.
1st Category Percentage:
The odds to get 5 out of 5, given that the 5 winning numbers are among the ones you have chosen in this system.

Full Development Columns:
The number of columns that would have been created, if you selected to play the respective full development system.
System columns location
Columns are reduced in a specific way, by the slips entry system and deducts them using the “Tables with positions of numbers” which are predetermined and always apply.
To locate your own combinations of 5s, corresponding to the standard system you have chosen, use the “Table with positions of numbers”.
Example
Participation with the standard system 45
Selected numbers: 7  (4, 10, 22, 25, 32, 38, 44)
To find the 5s via which you participate in the draw, just place the 7 numbers selected in ascending order in the positions of the table and see the columns that derive.

Permutations System
They offer the ability to combine your selections in 2 up to 5 slip areas.
The success rate depends on the number of correct predictions in each area (100% success rate is achieved, in case selections in all areas turn out to be correct).
The number of potential correct selections is marked in the "Codes" field of each area.
Participation in Permutations Systems is always in the form of ΑxΒ or ΑxΒxC or ΑxΒxCxD or ΑxΒxCxDxE and is achieved under the following conditions:
1. TZOKER number (1 to 20) is marked only in area A.
2. In each Permutation System, the sum of numbers referring to potential successful selections, in all marked areas, should equal 5.
3. The numbers marked in each field of 45 should not be the same as the numbers marked in each one of the other similar fields.
The rest of the slip areas, except for the ones the system is developed, must remain blank.

Group Play
About group play
You can participate in the game by playing a group slip with your friends (2 to 25 persons). Slip value is equally shared according to the number of participants.
The tickets issued are considered as independent entries and are handed out to the participants, who in case of win, collect their winnings separately. The sole requirement is for the quotient, when dividing the slip’s columns by the number of participants, to be an integer.
How to play with 4 simple steps
1. Visit an OPAP store with your friends
2. Fill in a TZOKER slip with numbers of your choice
3. Submit your slip, stating that it is a Group Play
4. Distribute the tickets among you (1 for each participant)
Advantages
• You increase the columns
Through the group play you join forces with friends. So the more players, the higher amount of slip columns played in the ticket.
• You share the cost
When participating in a group play slip, the cost is equally shared among the participants (e.g. 5 participants – group slip of 20 columns, 10€ value – each one of them will pay 2€)
• You collect your winnings separately
In case your group slip wins, the tickets are redeemed separately. Each player collects the respective amount, simply by submitting his/her own ticket at any time.
• You have fun with your friends
Group play is always more fun, don’t you think?
Quick Pick option
The field "Quick Pick" is available in every matrix area:
a. By selecting "Quick Pick" without marking any digits in a matrix area, the terminal generates a single column by:
• randomly selecting 5 numbers (1 to 45) and
• 1 TZOKER number (120)
b. By selecting "Quick Pick" and 1 number greater than or equal to 5 (field of 45), the terminal generates a full system by:
• randomly selecting numbers (1 to 45) as indicated and
• 1 random TZOKER number (120)
c. By selecting “Quick Pick” and 1 TZOKER number (120), the terminal generates a full system by:
• randomly selecting 5 numbers (145) and
• random TZOKER numbers as indicated
d. By selecting "Quick Pick", 1 number greater than or equal to 5 (e.g. 8) from the field of 45 and 1 TZOKER number (e.g. 3), the terminal generates a full system by:
• randomly selecting 8 numbers (145) and
• 3 random TZOKER numbers
e. By selecting "Quick Pick", a standard system code (e.g. 12) and 1 TZOKER number (e.g. 1), the terminal generates a standard system by:
• randomly selecting 15 numbers (145) and
• 1 TZOKER number (120)
Note: The selected number in the "20 numbers" field indicates the amount of requested TZOKER numbers and not the TZOKER number itself.
Consecutive Draws
By filling the relevant fields, you can participate with up to 94 consecutive draws (starting from current). Multiple selections work cumulatively and refer to all games, including PROTO.
Participation in PROTO through TZOKER slip
There is also the option to participate in PROTO (with up to 186 consecutive numbers), by marking the area at the bottom left side of a TZOKER slip.
Multiple selections (1, 5, 10, 20, 50, 100) work cumulatively (e.g. for 125 consecutive numbers mark 5, 20 and 100)
Note: In case of participating in PROTO through TZOKER, LOTTO, PROPO, PROPOGOAL slips, 2 different entry tickets are issued – 1 for each game.
Column Value
A single column (5 from 45 numbers & 1 TZOKER number, for 1 draw) costs 0,50€.
