Lamp Garden

Lamp Garden is a 24-level lamp puzzle; the garden starts at 3×3, grows to 4×4 in level 4 and to 5×5 in level 11. In most levels you turn off all the lamps; from level 16 on, some gardens ask you to light them all.

Step by step

1. Tap a lamp, or select it with the arrow keys and press Space: that lamp and the lamps above, below and on both sides of it flip.
2. Every tap uses 1 unit from the energy bar. If you don’t reach the goal before your energy runs out, you lose the level.
3. Stone squares arrive in level 7: they never light up or go dark, and you can’t press them. From level 12 on, lamps with an ✕ pattern flip along with their diagonal neighbors.
4. Finish in as many taps as the shortest solution to earn 3 stars. Your single hint shows the next correct lamp but caps your stars at 2.

Tips

• Pressing the same lamp a second time cancels the first tap; the order of your presses doesn’t change the result.
• A corner lamp has few neighbors; thinking about the garden from the corners and edges inward makes your job easier.
