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.
Before you spend another dollar on items and services like these, check with your public library. You will likely be surprised by what it offers for free.
