twyk vs 3D Slash

3D Slash and twyk are both easy ways into 3D design, but they build in very different ways. 3D Slash works like Minecraft: you add and carve away blocks, which feels natural to young makers. twyk works with smooth shapes and holes measured in millimetres. twyk is free with no paid tier; 3D Slash has a free tier with queued downloads and paid plans for more.
