And here we are - 5 minutes after midnight without a new Weekly Sale :)
Good night and prepare for a hot week.

I wonder...

Not sure if someone already posted this fact, but Summer Sale has started on Wednesdays the last couple of sales, and it has been on a Wed. the last 4/9 times (from the dates posted by the OP), so my bet is that the sale will start this Wed. June 8, 2022 this time.

2021 - - - - - 9-28 Jun - Wed. June 9
2020 - - - - - 27 May - 15 Jun - Wed. May 27
2019 - - - - - 30 May - 17 Jun - Thu. May 30
2018 - - - - - 4-18 Jun - Mon. June 4
2017 - - - - - 6-20 Jun - Tues. June 6
2016 - - - - - 8-17 Jun - Wed. June 8
2015 - - - - - 3-19 Jun - Wed. June 3
2014 - - - - - 13-29 Jun - Fri. June 13
2013 - - - - - 18 Jun - 4 Jul - Tues. June 18

Wednesday would be consistent with Warhammer sale (ends on Wednesday) and similar to the last year's date (in general I assume that recent patterns are more probable than years before).

Seems like I've found out when the Summer Sale starts - developer of Tunguska mentioned on the discord, that it will be discounted on Summer Sale "tomorrow' - I'm still trying to find out if it's today or tomorrow, because he posted it on 01:12 AM in my timezone, but it could be still Sunday in his timezone)

Here is the link, proving that I'm not lying ;)

The sale runs from today to the 27th:

Wow, almost all my wishlisted games on sale (not Old World though), and on top of that we get Alien Isolation with all DLC:s today! :)

Isn't it weird that current flash sales end in 17 hours? Which means – on Sunday.
Weekend flash offers usually lasted 72h – starting on Friday 15:00 and being replaced on Monday 15:00 (PL timezone).

Maybe they forgot it's weekend and set wrong timers?

This is the most likely explanation. After all, we're on GOG (:

We'll find out tomorrow. ;)

Well, you were right :D

Somebody at GOG: oops!

The Find Your Indie sale has special artwork and a bunch of stuff on sale so I think it should go on the list :). July 25 - Aug 1.

I'm not sure if it is just my memory but I don't remember this much stuff in weekly sales after the Summer Sale last year.

I don't know, I'm not sure, but, well, with 1000+ games discounted, 2 BYOB offers and dedicated page layout – you're probably right, it's big enough to be mentioned on the list. Added. Thanks!
