How do you deal with terrain tiles that keep getting knocked out of place? I'm interested to hear of your solutions. For what it's worth, here's mine.
During a game the other day, my opponent (a.k.a, "Ham-Hands") knocked the terrain tiles out of place just about every time he moved his units. That got me thinking about a convenient way to keep the tiles in place without: (a) damaging them or the board and; (b) spending a lot of cash. I initially thought of that blue sticky tack used for putting posters on wall but was afraid it might stain the tiles. Sure enough, when I went to Wal-Mart to buy some - sure enough - the package contained a warning about staining.
Luckily, on the same aisle as the sticky tack was a pack of "Clear Mounting Squares" by Scotch. This is the same clear, rubbery stuff used for the larger, pull-out advertisements in some magazines. A pack of 35 squares cost about $3 and they are reusable. I cut each square into fourths (a little piece will do just fine) and was really pleased with the results of my first game with them. They adhere well, are very thin/unobtrusive, and are relatively easy to remove. I saw no signs of staining or any other damage to the tiles or board. Best of all - there was absolutely no tile dispacement during the game.
The only drawbacks are the time needed to first adhere the squares to each tile and then to carefully remove the squares so they can be reused. I won't adhere the tiles every time I play but if I have the time and don't plan on playing more than one adventure, I'll definitely bring my sticky squares.
