Create a big scale (i.e. a long line) on the floor with masking tape. Mark one end as 'Great' and the other as 'Bad'. Let participants stand on the scale according to their satisfaction with the last iteration. Psychologically, taking a stand physically is different from just saying something. It's more 'real'. You can reuse the scale if you close with activity #44.
The team nominates stories for awards and reflects on the winners Source: Marin Todorov
Display all stories completed in the last iterations on a board. Create 3 award categories (i.e. boxes on the board):
Most annoying story
... 3rd category invented by the team ...
Ask the team to 'nominate' stories by putting them in one of the award boxes. For each category: Dot-vote and announce the winner. Ask the team why they think the user story won in this category and let the team reflect on the process of completing the tasks - what went good or wrong.
What would make the next iteration a perfect 10 out of 10? Source: Ben Linders
Prepare a flip chart with 2 columns, a slim one for 'Rating' and a wide one for 'Actions'. Everyone rates the last iteration on a scale from 1 to 10. Then they have to suggest what action(s) would make the next iteration a perfect 10.

When the team can't decide between two options, create a big scale (i.e. a long line) on the floor with masking tape. Mark one end as option A) and the other as option B). Team members position themselves on the scale according to their preference for either option. Now tweak the options until one option has a clear majority.

Start by giving a sincere appreciation of one of the participants. It can be anything they contributed: help to the team or you, a solved problem, ...Then invite others and wait for someone to work up the nerve. Close, when no one has talked for a minute.
