How to play
Organiser: Come up with the number of grey buttons in the jar, write it down and put it in a secret place.
Invite lots of people to guess the number of grey buttons, and make a small donation to take part.
Suggested minimum stake is £2 per go.
Players: Write your guess above, when all have been filled, the organiser will reveal the closest, winning guess.
The closest guess wins a prize (we suggest a percentage of the donations collected or your company or local
shops could donate prizes).
Supporting people with a brain tumour: Send the funds you have raised minus any winnings, to:
l brainstrust, 4 Yvery Court, Castle Road, Cowes, Isle of Wight, PO31 7QG
l Donate via Just Giving: justgiving.com/brainstrust
l Text your donation to WGRY16 £[amount raised] to 70070.
Your donation is vital in helping more of the 60,000 people living with a brain tumour in the UK
to be less alone, less afraid and more in control.
