I`ll describe basic idea and how it works below.
By the way, you can rebuild it to your preferences and adjust some of the rules.
Also you can do other amount of edges challenge like 100, 500 or maybe even 10000 if you wish to do so.
I'll appreciate if you'll share about your experience trying out this challenge.
Base Rules:
- You're starting with 1000 edges you must to complete before you can cum.
- In every 20 seconds you can have only 1 edge, not more (by this i mean it will count as 1 edge, you can do rapid-edges or riding it, but in a 1 minute you can`t count more than 3 edges even if you did more).
- you can watch any type of porn you like
- For edges you can use any toys, onaholes, flashlights, vibrators, smart-toys, e-stim etc. use your best one, swap them or use combination of them.
- You don't need to do it in a one day, take your time. The longer you are denied, the more desperate you are, the pleasurable it become!
- ruin your orgasm if you accidentally cum.
You need to multiply the amount of edges you haven't done yet to your multiplier depends on your chosen difficulty.
There are 3 base options for your multiplyer (difficulties) and one custom:
Easy = 1.2
Medium = 1.5
Hard = 1.8
Custom = use your preferable multiplyer bigger than 1.0
Example of how it works:
If you edged 400 times and accidentally get ruined, you still have 600 undone edges.
So in Easy difficulty you need to do 600*1.2 = 720 more edges before you can have full orgasm.
On Medium difficulty it will be 600*1.5 = 900 edges to do.
And on Hard it will be 600*1.8 = 1080 edges to go.
- Number of edges to do can go over a 1000 on hard difficulty, on other difficulties if after a ruin your number of edges exaggerates 1000, then start from 1000 directly.
There are additional modifiers (game mods) which you can choose to make your challenge more fun.
- If you want to change difficulty or game mod you should take at least 24 hours no touching and start new run from 1000 edges with new mods.
Game mods:
Base: Default mode without any additional rules.
perk: Maidenless Tarnished - no perk.
Edgerunner: Hold every edge for at least 15 seconds.
perk: Overstimulation - holding an edge for more than 1 minute counts as 5 edges but if you completly stopped (took your hands/toy off) during this edge-holding before 1 minute it counts as only 1 edge.
Painslut: 5 light/medium ballslaps/clitslaps after every edge.
perk: Loviatar's blessing - every additional 10 ballslaps/clitslaps counts as 1 edge. (5 slaps after every edge are not included in this 10 additional clit/ballslaps).
You can use this additional slaps when you want and how much you want, without limitation, so technically you can even complete this challenge only by slapping your balls or clit.
Anal-enjoyer: use buttplug/inserteble during edges.
perk: Backdooring - edge from only anal stimulation counts as 5 edges (strongly recommend toys with vibration).
Honour Knight - if you cum/ruin, start from 1000 edges despite on amount of edges you have done, in this mode you don't need edge multiplier.
Perk: Strong will - that's the only thing that you need.
Cumslut: (Penis needed!). After 10 edges, check your cock and eat all precum. If you ruin or cum, eat it all.
Time limit: For every 10 minutes that passes, you must add one extra edge. If you are playing on hard, this number can keep going up. Otherwise 1000 is the limit.
Soft gambler: Each time you complete 100 edges, flip a coin. Head remove 50 edges, Tails you add 50 extra edges.
Know thy place: Every edging session must be done kneeling, with ankles tied and one of your hands tied on your back. You must tie your balls, if you have, or your boobs. Use a gag or something in your mouth.
Nipple-play: attach clamps and pull off after 10 edges, then turn 90 degrees and reattach.
Alternate sides after each 10.
Feet-lover: Can edge only on pics or parts of the videos with close-up feet on display. You need to edge at least 1 time per foot on each pic with close-up feet.
Ass-worshiper: Can edge only on ass pics or ass-worship videos. Every glance at pussy will be punished with 10 slaps.
Special Game mod
Properly Fed: You must pick one of the feed posted by someone and do you edges accordingly. That means watching whatever the person choose.
Feed example 1: Do your edges by going into https://www.sex.com/en/shorts and scrolling down. At least 1 edge per shorts.
Feed example 2: You may only edge to swimwear shows on youtube.
Feed example 3: Anything you watch must come from this playlist https://spankbang.com/aydby/playlist/pmv
Share your ideas and impretions. Feel free to add your personal mods and remake this idea to suits you the most.
Wish you good luck and a lot of pleasure!

(More of what you liked with less of what didn't work.)
... it's not 
50 edges minimum and 100 edges maximum must be performed in order to complete this challenge. You MUST stop and complete the Task after reaching 100 edges, but, after 50, it’s up to you when you want to “complete” the Task and move on to the next one.
…
So, you can be “safe” and choose more “safe for work” sources … OR … you can choose to be horny and go for the “juicier material” and suffer the consequences. 
...
Knowing what I know now, I would have taken like 5-10 more minutes and doubled or TRIPLED the number of videos to pad out that task 
... but it's good! 
), but ... probably 10-20 minutes "minimum session time" ... yeah ... I think I'll call it: "minimum session time" ...
