Use ←/→ (or A/D) to move the cursor across the columns.
Press ↓, S, Space or Enter (or the DROP button) to drop the current node.
Three or more connected nodes of the same type (horizontally or vertically) will vanish.
After nodes vanish, the ones above will fall down – this can trigger cascades for extra points.
The SYSTEM LOAD bar increases as the grid fills. Cascades reduce it in Standard/Hard; in Zen it's very forgiving.
In Habbu, your goal is to completely fill the grid – the system load is only visual and grayed out.
