  1. Business Opportunity in Ruvol

    I have invented a Board Game [still unpublished and not yet out in the market] that I believe is guaranteed to be as challenging and exciting as CHESS. I called it “RUVOL.”

    It is my hope that one day Ruvol may surpass chess as the “Number One Board Game in the World.”

    The weakness of chess is it always starts in fixed positions that the opening moves become “memorizable.” In fact, not a few have so mastered the moves that they can play against their opponents “blindfolded.” It is for this very reason that the great Bobby Fischer introduced his so-called “Fischer Random Chess,” where the starting position of the pieces is “randomized” to make the memorization of openings impracticable. Fortunately, it is also for this reason that I invented Ruvol where “every game” has been calculated to be a challenging one to play.

    HOW IS RUVOL PLAYED and HOW YOU CAN MONETIZE IT?

    I detailed everything in my YouTube video. Here is the link: https://www.youtube.com/watch?v=jcqth0m3-R0

    BIG MONEY POTENTIAL IN RUVOL!

    It is worthwhile to note that the people who play chess will be the same people who will play Ruvol. In my Google search, I learned there are around 800 million chess players in the world. Even just a small percentage of these 800 million is good enough to earn big money from Ruvol either as an ONLINE GAME BUSINESS or as a PHYSICAL PRODUCT DISTRIBUTOR.

    Thanks and God bless!

  2. Avoid using 'simply' and 'simple terms' if you don't also think your audience is simple. Would be better described as 'everyday/ordinary/straight-forward' etc.

  3. It is so funny seeing Gray explaining stuff that took a whole exam at university in a simple and coincise way, but on the other end is nice to know the topic in advance 🙂

  4. Great explanation Gary. This is the best balance between actually explaining the flaws and not getting too technical, that I've seen thus far. I finally can share a full explanation with my father. Thanks!👍

  5. I always had my doubts about CPU Caching and it's perks. It's like a fridge that has vegetables and fruit in them, start rotting if you do need eat them soon enough. Freezing them is another approach but that is not really caching is it? I take one fruit out every day and at a certain point i will have to add more fruit to the storage. When exactly Depends only on my action to do so, prices and availability. Now i consider to buy 1 fruit at the shop when i want to eat one. No rotting ever.

  6. Thanks professor !! For these amazing videos . I always wait for them. I have a request . It would be great if you suggest some books, websites, articles and relevant links for further reading . This would be of great help for exploring more on the topic .

  7. Android authority, I have a Galaxy j3 Luna pro and my screen keeps locking after 10 seconds of inactivity I went to my settings and changed the screen timeout to 2 minutes but it still does it please help.
