Homescapes / Gardenscapes Ads

Maybe you've seen them - in the ad you see some kind of disaster scenario, and you are to make choices to avoid catastrophe. Sometimes it's a leaky faucet you can fix with either a wrench or a jackhammer. Sometimes you have to move levers to "help her escape" like in this screenshot:

Many of these ads include a playable demo, and the gameplay can be pretty silly and fun.

If you click through the ad to download the game, however, you're in for a surprise.

Because you'll get an entirely different game. A Candy-Crush-like match-three-in-a-row puzzle game.

That's right - the ad shows gameplay, and has a playable demo, of a game that doesn't exist.

Homescapes (and its sequel game, Gardenscapes) can boast that it has huge download numbers, and can call itself "popular", but the downloads are based on 100% false advertising.

I'm not even sure how this is legal at all!

Have any of you had this experience?
