There’s nothing more enjoyable than happening upon a great BOI seed that gives you OP tears from the outset and allows you to obliterate your foes. Luckily, some people take note of their seeds so that others can enjoy them, too.
Seeds change depending on the console and the version you’re playing, but we’ve scoured the net and have tried to find the best Repentance and Afterbirth+ seeds. So, here are the best Binding of Isaac seeds available right now, with what to expect in each run. The items found in some of these seeds may change slightly depending on which items you have unlocked. Use the contents menu to skip to the relevant section for you.

The Best Binding of Isaac Repentance Seeds
As the most recent DLC, it was harder to find a lot of the best Binding of Isaac seeds for Repentance, but there are still plenty to be getting on with. As of time of writing, Repentance is only available for the PC, so all the Repentance seeds below are only for PC.
Items: Ankh, Bible, Tech X, Mutant Spider, Guppy’s Collar, Sausage, Faded Polaroid, Flat File.
Notes: Run works well with Azazel. Find the secret rooms to make the most of the run (the Bible is in a secret room on Depths II).
Items: Rocket in a Jar, Goat Head, Dead Cat, Soy Milk, Blood Clot.
Notes: Very fun Isaac seed that leads to some interesting synergies, particularly if playing as Azazel. It’s the run that keeps on giving and continues to get stronger the farther you get.
Items: Inner Eye, Almond Milk, Brimstone, Pentagram, Brain Worm.
Notes: Very OP run that will leave you with triple Brimstone and homing shots to boot.
Items: Mutant Spider, Proptosis, Brimstone.
Notes: Brimstone is on the 4th floor and the Brimstone is on the 4th floor’s Devil Room.
Items: Inner Eye, Mutant Spider, Squeezy
Notes: This is a good seed if you like multiple tears in one shot. It gets good fast and you can tailor it how you like after getting these strong items early on.
The Best Afterbirth+ Seeds
PC Afterbirth+ Seeds
Here are the best Binding of Isaac seeds for the PC in the Afterbirth+ DLC.
Items: Inner Eye, Mutant Spider, 20/20, Tammy’s Head, Multidimensional Baby
Notes: Fun with any character but Tammy’s Head makes Azazel the character of choice in this one.
Items: Brimstone, Mutant Spider, Magic Mushroom, Lost Contact
Notes: Very powerful seed with great projectile protection from shielded tears. Brimstone is in the second floor devil room.
Items: Ludovico Technique, Small Rock, Cricket’s Head, Spider Bite
Notes: A great seed for Azazel as you get Ludo on the first floor. Small Rock is found by bombing the marked rock on the first floor, and Cricket’s Head is in a stone chest on the second floor.
Nintendo Switch Afterbirth+ Seeds
Here are a few of the best Binding of Isaac Seeds for Switch:
Items: Mutant Spider, Proptosis, Brimstone, 20/20, The Mulligan, Jacob’s Ladder, Spirit of the Night
Notes: One of the most OP seeds I’ve tried. Pyromaniac also turns up at some point which helps the low number of health upgrades.
Items: Godhead, Book of Sins, Capricorn, Judas’s Shadow, Athame, Guppy’s Collar, Growth Hormones.
Notes: Best played as Eden in order to get Godhead as one of the starting items. Would still be a strong seed with other characters, though.
PS4 Afterbirth+ Seeds
Here are some fun BOI Afterbirth+ seeds for the PS4.
Items: Guppy’s Paw, Guppy’s Head, Guppy’s Head, Hive Mind, BFF
Notes: If you like Guppy, you’re in for a treat with this seed. Needs to be played as Isaac in order to get Guppy on the first floor. In the curse room, open the 3 Red Chests, take Guppy’s Paw and then touch Guppy’s Head and replace it again for the D6. Re-roll the head into Guppy’s Collar and let the fun commence!
Items: Guppy, Wafer, Inner Eye, Epic Fetus
Notes: Make sure to visit the Dice Room on the first floor!

Great! Thanks for sharing
I have a good seed too. From start you get Dr.Fetus and TNT to blow up bombs when press space button. Seed: 63PW V1FG
Man, that sounds like a good one. Thank you for sharing
I just got the best seed i found so far, i was playing random seeds to get some characters (such as samsom), when i got the seed i got 3 characters, samsom, eden and magdalene, the seed is N0RJJ1NT
Nice one, I’ll check this one out shortly. Must’ve been good to get all those unlocks. Thanks for sharing the seed
QLP3HSJ4. Greed Mode. First shop has a fire with a nickle, that key gets you tech X in the item room. First devil room has two guppy items – second and third floor devil rooms both have guppy items as well (other items were the mark and penagram). Third floor item room has hemolacria. Very OP run right from the start.
That sounds incredible. I love a good Greed run. Thanks for sharing!
greed mode op seed (recommended for lilith): 80M6 8SMF
op damage, 10 heart containers, 9 volt and 7.5 volt, and it makes so you can spam incubus in ultra greed, recommended
I don´t now why or how but the seeds didn´t work for me 🙁
Hmm okay, I’m gonna have to double check these and update if that’s the case. Thanks for commenting
I play on Steam with BOI Rebirth and maybe one out of 20 works. Maybe include a version number? Mine is 1.7.8a
Yes good idea mate, will include that on all future seeds. Thanks!
