Blast the Past (the "competition") is open to all players worldwide including employees of TalkTalk Group and their families. All entry instructions form part of the terms and conditions, which, by taking part, all entrants will be deemed to have accepted. TalkTalk reserves the right to change the terms and conditions or discontinue the competition without notice.

Only scores posted before 23:59 GMT on 31st December will be counted towards the competition.

The prize is a Sony PSP Go! (colour may vary). We reserve the right to offer a cash alternative to international players (based on the UK RRP of a Sony PSP Go!). The Sony PSP Go! will be a UK version.

Any personal data relating to entrants will be used solely in accordance with current UK data protection legislation and will not be disclosed to a third party (view TalkTalk's privacy policy).

The winner of the competition will be the highest scorer on each of the three games at 23:59 on 31st December. Where a draw occurs on a particular game, one winner from the joint leaders will be selected at random. Only one prize will be awarded per player - in the event that one user tops the leader board for multiple games, then those players in second place (for all games involved) will be put in a hat for the remaining prize(s).
