Keel: Open Water

This is a falling-block stacking game with a twist: weight matters. Slot each dropping container into the hold to clear lines, but every block shifts the ship's balance. Let one side grow heavier than the other and the deck heels over until it tips past the point of no return.

• Move and rotate falling cargo to fill rows
• Complete rows to clear them from the hold
• Spread weight evenly to keep the ship level
• Heel past the tipping angle and it's game over

• Desktop: Left/Right arrows move, Up rotates, Down soft-drops, Space hard-drops
• Phone & tablet: swipe to move, tap to rotate, swipe down to drop

• Mirror your stacks, load the light side to answer every heavy drop
• Clear lines fast to lower the whole load and reduce list
• Don't chase a perfect fit if it tips the deck; balance beats tidiness

An original game about a problem real ships genuinely have. Cargo does not merely need to fit; it needs to be distributed, because weight on one side heels the vessel and a list past a certain angle is unrecoverable.

Its puzzle ancestry is the falling-piece packing game descended from Tetris — pieces arrive, you choose where they go, space runs out. What it adds is that placement has consequences beyond geometry.

That makes a perfectly packed hold potentially fatal. A tight fit that puts mass to port is worse than a loose one that keeps the ship level, so the optimal play is constantly arguing with the packing instinct the genre trained into you.

Keel: Open Water is an original arcade puzzle that fuses falling-block line-clearing with a real balance mechanic, a free browser game and the calm starting point of the Keel series.
