Games platform Humble Bundle is making some changes to its offering, not least how much consumers can donate to charity.

In a post on its website, it was revealed that the firm was going to be capping donations to charity to 15 per cent, if users click on the new "Extra to Charity" option when buying a bundle. Previously, you were able to specify the amount that went to Humble and the amount you wanted to donate to charity with some sliders. Humble has already tweaked this option for some customers as a test.

"About a month ago, we turned on a test that hid sliders for certain customers," Humble wrote.

"This test was part of our bigger plans to make updates to the bundle pages, but without any context, we see how it raised questions and led to confusion for the community. We apologize for that and appreciate everyone who wrote in to ask us about it. The lesson for us was that we should have been more proactive in communicating the test."

Humble continued: "We’re grateful to all of you for building a community that cares so much about supporting charity. By unifying the way that Bundles, the Store, and Humble Choice all support charity, we can continue to create and expand bundles that power incredible causes around the world."

Since 2010, Humble has raised $195 million for various charities. In 2017, Humble was bought by IGN owner Ziff Davis, with founders Rosen and Graham departing the company two years later.
