Humble Bundle offers downloads of the Humble 4-Game Bundle for Windows and Android 9 for whatever you want to pay. If you opt to pay the bare minimum of $1, you'll get Broken Sword 2: The Smoking Mirror, Bridge Constructor, Type:Rider, and Ravensword: Shadowlands (pictured). That's $37 under the lowest price we could find for downloads of these games elsewhere. If you pay more than the average, currently $3.61, you'll also get Kingdom Rush and Knights of Pen & Paper +1 Edition, a total price low by $54. Your contribution can be donated to charity (EFF or Child's Play), Humble tip, the developers, or all. Deal ends April 15 at 2 pm ET.
Note: These games require a Steam account for activation.
You don't even need an AARP membership card to qualify for the "senior" discounts at these retailers.
