Participant has the opportunity to enter the 6 numbers in advance before Wednesday 06:55 GMT (off-line), or participate in the lottery on-line. Enter a number — guessed it? Enter the next one. (If you did not guess — It is not allowed to enter anything more.) And at any moment he might to go off-line (for example, he is hurrying) entering the rest numbers. That is, if participant entered two numbers, guessed them, and then he has to go somewhere — he enters the rest numbers and goes out. Then, later, he looks at the result.
He also may change the offline regime into online at any moment. That is, he entered all 6 numbers before the start of the drawing, backed on the 4th number and saw, he guessed the previous three numbers! Then he can participate on-line (if he wants). And change the numbers already entered (starting from the 4th).
There is a window for 6 numbers and two buttons in the PO in LOTERY: CLEAR and RANDOM NUMBER GENERATOR. You can enter numbers in the window. CLEAR — all the numbers disappear.
RANDOM NUMBER GENERATOR — generates a random number (it can be difficult to choose for some people :-)). A participant can change everything a hundred times before 06:59 GMT. And further during the lottery (if he participates on-line).
I want to recall that the person may enter the whole number at any moment and go somewhere, and then coming back continue to change them. (That is, he guessed the first two numbers, then walked away, during this time the third number was played. Did he guess it? So, he can further change the numbers again. Starting with the forth.) Also he can fill in the rest not entered numbers with a random number generator.
