Is it possible?

I have had 100% chance a few times during my years on SG, so yes, it's possible.

Yes.

If you are the only entry in a giveaway....yeah :)

I do think that it must be the only giveaway ending on that day tho , or it may lower the % in the stats page

There have been a couple 10,000 copy giveaways so yes

Happened to me in a private GA with many available copies: 50 copies, 25-ish entries.

I had 100% prediction for this Sunday. I didn't win and after the fact it was lowered to 27%.

Yes you can

Mass ga - with for example 10k copies of geme, when there is less participants than available copies :) Experienced it once.

According SG stats for me 3 times in this month: 2nd, 16th, 18th. Also 1 time 99% - 8th, 97% - 7th.

100% quite a bit, depends what you enter.

1 entry = 100%

Easily achievable in group giveaways especially if groups are limited to a certain number of people.

Yes, once I had won a giveaway while I was the only entry in it. It was a bit unfair that way though. I like being lucky, not winning giveaways with only 1 entry. xD

One time i reach 100% chance AND......TUTUTU >>> I don't WIN! Yes, it's possible too

PS: but - at once i win 11 keys (different games) concurrently from big train ^_^

yep

On the other hand, you can go home empty-handed after a day with 80%+ chance… =(
