A hard-working garden gnome is in charge of keeping every plant alive. In Garden Master you walk him around with the arrow keys, press Space to water, and chase off sneaky gophers. On a phone, drag the gnome close to a plant to water it. The game is endless, so the aim is a high score.
Two kinds of plants need different care. Sunflowers drink a lot and follow the sunbeams, while misty ferns are less thirsty and spread mist to their neighbors. Refill at the water barrel before you run dry, and pick up golden seeds to unlock upgrades. Classic Snake has the same keep-going-as-long-as-you-can feel.
