# Timing and ticket sales

**The number (N) of lottery tickets for each round is limited. Ticket sale for the corresponding round ends instantly when sold out. However, please note that the number of tickets for one round depends on the previous round.**

**●      If tickets for the previous round are sold out, the number of tickets for the new round will be doubled.**

**●      If not, the system will halve the number of tickets for the new round.**

**The countdown timer for each round will start after 1 hour since the last draw and end in 12 hours. Whenever somebody purchases or N/8640 new tickets are purchased, 5 additional seconds are added to the countdown timer. Ticket sale ends when the countdown timer goes down to zero or when all tickets are sold. The Timer is limited to around 24 hours.**\ <br>
