There is a special kind of fun in watching something big fall down, and TNT Sandbox is built entirely around it. It is a voxel demolition game: a world of houses, towers and pyramids made of blocks, plus a big supply of TNT. Place the charges, hit the ignite button, and watch whole structures crumble in spectacular fashion, block by block.
It is made by Kachki Productions, and it was their first game on Poki. The blocky style will remind you of Minecraft, but the focus is very different. Here, nothing gets built for long.

Campaign mode is for the careful demolition planner. You get 10 demolition contracts, each with a building to bring down. Where you place the TNT matters. A charge in the wrong place only knocks a few blocks loose, while a charge at a weak point can bring the whole building down. Thinking like a real demolition engineer is the key.
Sandbox mode is for the chaos lover. It gives you 6 maps and zero rules. Build whatever you like, blow up whatever you like, and try out every crazy idea. There is no wrong way to play.

The voxel physics are the star of the show. Every block flies on its own, so every explosion looks a little different, and a big collapse is a joy to watch. Whether you plan carefully or just want to see things blow up, TNT Sandbox delivers.
For destruction on a bigger scale, try City Smash or the planet-sized Planet Destruction. For more blocky fun, there is Eaglercraft 1.8.8. And for physics destruction with cars, play Demolition Derby 2. Now place the TNT and press the button.
