ROCK FALL is based on the road traffic warning sign for falling rocks - a sign that seems a bit less useful than somebody getting up there on that cliff and actually doing something about it... Anyway, the rocks are falling and it is your job to stop them hitting the road below, or at least stopping them hitting the road below too many times and breaking it. Smash the rocks by clicking or tapping on them (not so easy in real life of course) - they will turn into snowflakes and float gently down into nothing.

There are 4 rocks to stop and not much time to do it (if you want to get a good score and get on the leaderboard). This game is fun and fast and requires good reflexes and a good strategy. Plan to break the smaller rocks first if you want a good score because the rocks fall faster as the game progresses. It also helps to decide where on their path you plan to click / tap the rocks.
