Each team will be provided with a visual clue, which will be covered by six blocks.

1 2 3

4 5 6

Six questions will be asked to each team of which each will carry10 marks.

By answering each question, the team can remove a block onthe visual, according to their choice.

A team can further remove additional blocks, even though they didn’t answered the questions. But for each additional block thus removed, they have to sacrifice 10 marks.

The last question will be identify the visual, which will carry 40 marks.

Only the last question will be passed to other teams, which, if answered correctly will provide 10 marks. The other teams won’t be permitted to remove any more blocks.
