3D Lemmings is played by using four different, movable cameras to fly around and get an overview of the level. While some levels have fixed cameras, most of the time they can be freely moved at any time, although without the ability to tilt up or down. Another viewing option is the "virtual lemming" (VL) which allows the player to see through the eyes of a selected lemming.
All skills from the original game are available, with one new one: the turner. A turner is similar to a blocker, in that he stands in one place and can only be removed by being blown up or dug out from underneath. However, instead of making other lemmings turn back, he directs them 90 degrees either left or right, as chosen by the player. Diagonally positioned blocks in levels will also make lemmings move left or right (basically reflecting them).
One of the by-products of being 3D was the importance of the camera-handling. Even though most of the levels didn't need complex camera setups, some levels could only be solved if the player was skilled enough to move the camera in the correct way - or by using the Virtual Lemming mode. For example, one level featured a massive indestructible block of wall with the lemmings arriving on top; the only way the player was able to deliver the lemmings to the bottom floor was by digging through a certain part of the block which was left destructible, and the only way to handle that was to use the VL mode, because the player was unable to fit the camera through the hole. Some levels included rooms or halls where the camera couldn't go into (or come out from) and the player had to peek in through windows or use VL mode.
The release rate buttons, i.e. to increase or decrease rate of lemmings; instant replay mode; and fast forward button all return from previous games. Levels are once again divided into four difficulty settings: Fun, Tricky, Taxing and Mayhem. There are 20 levels of each setting, with 20 more practice levels to learn about different game elements. Each level has a set amount of lemmings again, and can be returned to through the use of passwords.
Cutscenes are shown at the end of certain level milestones, which feature lemmings from the various 3D Lemmings themes (army, computer, etc.).
