While there are many websites that claim to offer The Binding of Isaac

(especially on Chromebooks) and do not support modern DLCs like Afterbirth Repentance Risks and Safety Malware & Phishing

You won’t find a legitimate, full, unblocked, no-download version of The Binding of Isaac . But the is a fun taste — and if you love it, support the developer (Edmund McMillen) by buying Rebirth on sale for as little as $5.
