Tetris, but with rubbish instead of blocks. Basically. It’s hard to explain, partly because I don’t think I quite understand it yet. You can smash stuff, burn stuff (bad for the environment) and, um, rot stuff… or something. You need to dispose of the rubbish without letting your bin overflow and, er, that’s it. It’s great fun and will either be much better when I understand it fully or just lose some of its mad charm. I think the £3.99 price is probably very fair.
