Interlocking Tiles

I created an interlocking tile system inspired by Wylock's Armory, video #095, CardboardLOCK. You can cut dozens/hundreds of cardboard chits to size and that absolutely is an acceptable and free way to do it. You really don't need chipboard, although it would give you a consistent thickness you probably won't find in cardboard for around $8 on Amazon

 

Looking at time/cost balance I personally decided that $8 was, in general, just fine with me to have an interlocking system, but I'd still be faced with cutting, gluing, and waiting for glue to dry so I looked for other means of getting it all done much more quickly without spending a lot more money. Enter dual-adhesive foam mounting squares. 

Interlocking tiles have Bump Resistance +3

Tip: I've found that if you use a generic drawer liner sheet the cardboard tiles stick pretty well as an alternative/supplement.​

Supplies

 

Notice: Although I try to update all of my links & prices at least once a month, Amazon sellers may change or remove the particular items or prices since the time they have been listed here. The items I have listed are the best that I have found at the time, but any item matching the general description should suffice for this project.

 

I've broken these down by size and then by part. In addition, I have added the keywords I used to find these items if you want to do your own searches or in the event that the seller has changed/removed the item listed below.

 

  • Cardboard - $0-6 - for the bottom of the interlocking section and chits to hold them together

    • Keywords: cardboard

Corrugated Cardboard
  • Box cutter $4 - I find the smaller ones to be perfect for the shortcuts needed

    • Keywords: box cutter

Box Cutter

 

 

  1. Cut cardboard to the size of  each tile you want to interlock

  2. Place a 0.4" mounting square a 1/2" inwards from each corner & one in the center of the tile

  3. Remove the backing from the top of mounting squares

  4. Line up and press the same-sized dungeon tile on top of the base (don't press too hard!)

Assembly

Tiles: 2x2​

  1. Cut cardboard to the size of  each tile you want to interlock

  2. Mark where the walls are (1/2" inwards) and if applicable, also 1" inwards from the edge. It's easiest to just draw straight across and no one will see the lines anyways.

  3. Place a 0.4" mounting square at each place where the outer edge meets the wall mark (edge against inside side of the mark)

  4. Center and place a 0.4" mounting square in the middle of each of the mark lines (centered 1" inwards from the edge) and if applicable, wherever if could use additional support

  5. Remove the backing from the top of mounting squares

  6. Line up and press the same-sized dungeon tile on top of the base (don't press too hard!)

Tiles: Bigger than 2x2

  1. Cut cardboard to the size of  each tile you want to interlock

  2. Place 3 0.25" mounting squares along each short edge (You may only need 2, but I find 3 gives me a more comfortable sense of firmness)

  3. Remove the backing from the top of mounting squares

  4. Line up and press the 1x2 dungeon tile on top of the base (don't press too hard!)

Tiles: 1x2+

  1. Measure & draw a grid 1.25x1.5"* on cardboard. Each 1.25x1.5" rectangle will form a single chit

  2. Subdivide and draw the 1.5" sides into 3 0.5" sections

  3. Subdivide the 1.25" side in order as follows; 7/16", 3/8", and 7/16"

  4. Cut out each 1.25x1.5" chit section

  5. Cut all 4 corners of the chit where from where the subdivided sections are marked

*You'll need 1.25x2.5" chits for the 1x2 tiles since there's no place for a chit to anchor
