    Came quickly, high quality material. Slight offset to board art for some cube spots, but still highly functional. I am very happy with my purchase.

    The player mats in Terraforming Mars were a bit of a pain with how tight the tracking numbers were scrunched together. A good knock to the table or accidental swipe of the sleeve had players reconstructing their production numbers. This overlay fixes all of that. The cubes fit nicely into the slots, leaving no doubt as to their value when the overlay is lined up. They improve the game experience quite a bit.

    Great product! Terraforming Mars is a fun game, but table bumps can ruin it. This product saved the day! The only issue (a small one) is that there is no way to fix the sheet to the overlay so that it slides a little (we have a rickety table). That being said, there is nothing to stop you from fixing it yourself with very light and reusable adhesive. Slides are not a big problem at all though because the overlay keeps all the resource cubes in place and there will be no rage quits from losing track of all your resources. We’re terraforming a new world here! This will make it easy.

    Also, delivery was prompt, and replies to my questions were cordial and quick. This company is fantastic!

    When you have an important task to do, the right tools are necessary! And Terraforming Mars is no exception! In our first game we saw the need for an overlay on our player mats – and the BBI engineers were quick to provide the exacting tool we needed! Within days they provided our Terraforming Specialists with overlays that worked perfectly. They are now an essential part of our great mission to terraform the red planet! You will find will provide you with excellent, prompt service. Very pleased with this product

    I was extremely disappointed with this overlay. Although it seems it was designed with love, what is described as a “slide offset” turned out to be a rather significant one. Almost none of the cubes fit above their designated spaces, and this caused confusion and really made me very frustrated. I respect with the creator was trying to do, but after seeing how poorly designed this was I had to buy a different product.

    I have recently bought five of the playmat overlays for my copy of this game and am very pleased with them.
    When you are placing cubes on the mat they only perfectly cover the first row, but this is down to the fact that the mats in the game have the resource meters very close together. The overlays themselves are designed as best as they can be and have been brilliant at keeping all the cubes in place as you play.
    A great addition to a game that sees a lot of play and well priced.
    Get yourself some, you won’t regret it!

    Doesn’t work with what came with the game unless you print off new player boards.

    Keeps your production levels intact along with keep your resources separate. Was well worth the investment.

    These boards are very high quality; clear, cut cleanly, impressive. But, they do not match the player boards in the game! If the buyer does not look at the pictures carefully, they will have a very disturbing surprise. Perhaps the seller should make note that there are 3rd party graphics (require printing) available that match the overlays at BGG. I paid nearly $50 for these and I want them to match! So, I had to print extra boards (on paper), laminate them, and I think I’m going to now glue them together.

    I’ll echo what was said by others. Product is very nice, but it does not match the printed mats that come with TM. It also does not come with a back (unlike one other version from a different 3d party vendor), which was not readily apparent. So, as a stand-alone, it really didn’t match my expectation.

    I will probably print replacement boards and attach them to make it work. But I didn’t buy these expecting the need for a bit of arts and crafts

    Device worked great to organize cubes on the player mat. I would recommend. The design does not fit to the included mat which is disappointing but I can see why it needed more room. Mat to use as a background can be found on BGG terraforming mars file section.

    Wow, we LOVE playing with these! Just as the Robinson Crusoe overlays perfected the RC game experience for us, these overlays have perfected the Terraforming Mars experience!

    Regarding the offset, it seems to me that there’s no other way around the fact that the two rows of cubes on the player mat are right next to each other! We did end up printing the player boards from BGG that are a perfect fit for the overlays — printing on photo paper makes them look amazing too! Highly recommend!

    I bought these and already knew to print new matts. This is a great remedy, but do wish they had a backing to them. I ended up taping them to my sheets but wish they would have come with a backing for the sheet. At least I can always reprint if something happened. Great product!

      Jeremy, Glad you like the overlays. We understand about the backer boards. We are working on a solution to that issue. We want to be sure it is a solution that will enable you to have the security of a backer board, but won’t cause additional problems. Permanent backer boards can cause damage to the player mats, and can be an issue when there is a spill. It’s important to have access to your player mats for cleaning and drying immediately when that happens. I can assure you when we release backer boards, they will be compatible with the overlays you have already purchased.

    I was really looking forward to these. I expected that the “slight offset” would not bother me. However, the offset is not slight. It’s significant and these are nearly useless with the original mats. Will need to print new ones. But how do I keep the new mats sturdy? Ideas would be great.

    • Elaine Rigby

      Hi Christian, I’m sorry that you are disappointed in the overlays. We do our best to show the offset in photos on the website. The player mats that are available on board game geek for printing are best printed on card stock. We printed our personal copies on 100# card stock, I am sure 80# would be fine. At print shops like Office Max it can be called Color Copy Cover paper. If you don’t have good card stock easily available to you, others have laminated their copies. The last idea, that has been used is to apply the player mats that you have printed on regular paper to a backing, such as spare file folders cut to fit.
