Nintendo has today stealthily released a brand new entry in Intelligent Systems's Pullblox series, and you can download it and get a handful of levels free of charge.

Fullblox is absolutely free to download, and you can initially play seven puzzling 3D stages without spending a penny. Thereafter, you can purchase four packs of stages: the all-rounder Playtime Plaza (100 stages) pack for £4.49; and Scuplture Square (50 stages), Fortress of Fun (50 stages), and NES Expo (50 stages) for £2.69 each. You can purchase all 250 stages for a special bundle price of £8.99, and if you manage to complete them all, you'll unlock the ultra-challenging Perilous Peak puzzles.

Just like its predecessors, Fullblox has you control Mallo as he pushes and pulls large blocks into place so he can reach the top of each stage. It sounds simple but its remarkably addictive and rewarding formula has won over many fans since the first game. The unique selling point this time around seems to be that Mallo can push and pull blocks from all directions, not just the front.

There is also the full range of stage-building and sharing options.

Check out the launch trailer for Fullblox below.
