How many winners per week

This counts people who won money for an answer offered during the specified week; this chart does not count those who offered answers but won no money.

To generate these charts, we use the excellent RGraph library. Please be aware these charts rely on HTML5 features (such as canvas) and therefore you must use one of these modern browsers:

• Mozilla Firefox 3.0+
• Google Chrome 1+
• Apple Safari 3+
• Opera 9.5+
• Microsoft Internet Explorer 8+ (see note)
• iPhone (text support from iOS v4+)
• iPad (text support from iOS v4.2+)

If you don't use a modern browser, you will not see the chart.
