Spinaltap had it right

To celebrate the 2nd anniversary of the game, we are introducing the special Dinotap boost tier amplifier incubator. As you can see, the numbers all go to 11. While most dinos only go to 10, yours can go one higher. Most blokes are going to be playing at ten. Tier tens across the board. When you’re all the way up to tier 10, where can you go from there? Nowhere. Exactly. What we’re offering with this special limited time offer Dinotap boost tier amplifier incubator is when you need that extra push over the cliff, you can take your dino one stronger, tier 11. These tiers go to 11.
Sales unlimited for the next five minutes.
