OK, I know you already know the basics of setting up your tower. We will try to refine it.
Think of the blocks in the Viking tower as cells. Cell # 1, the top block will USUALLY contain 1-5. Cell # 2, the second block holds 6-10, cell 3, 11-15. If you give the vikings a block they will NORMALLY place it in the corresponding cell.
In addition to getting the 41-50 blocks for our tower, we should attempt to get the following numbers in the Viking tower.
1, 2, 9, 14, 16, 28, 35, 37, 38, 39, 40. You will see eleven numbers, but one is also between the towers waiting to be taken.
There is nothing magic about those numbers other than being spaced apart. I always try for 1&2, and also 37, 38, 39, 40.As for the others I'm sure 8 would work as well as 9, 13 is as good as 14.
When you are setting up your tower you use the blocks you want to keep, to push out the ones you do not want. You should notice that there is NOT a number that will fit in the Viking # 5 cell (21-25). The 5th and 6th cells are the key to having a SAFE Viking tower. You should set up so that one of those 2 cells is vacant. The way to do this is to watch where the vikings put your GOOD blocks , when they do NOT put them in the proper cell. What you want the Vikings to do is put your 49 or 50 in their 5th or 6th cell and get rid of the one that fits in that cell.
If you try to collect the above numbers plus 41 - 50, you may lose but it will be very early in the game.
If you are successful in collecting all the numbers it will be impossible for the Vikings to beat you. In the above sequence you can substitute 22 for 28, as long as either the 5th or 6th cell, one or the other, remains vacant.
After you have tried this system for awhile, you will understand why having both the 1 and 2 blocks is important
Try also to keep the same numbers every game you play. It helps you know what block is where. Try this and let me know how it works. I also have a video of one set up that I can send you if you like. It is a pretty big file. I have shown this system to Jonas and you can see he has improved his play. Good Luck & best regards, lummox.
