Questions
What is Hazard Heights?
Hazard Heights is a physics block-stacking game for iOS and Android. Falling tetromino bricks land where gravity and friction put them; you build a tower, survive the chapter's hazards, and keep it standing long enough to hit the target.
Is it free?
Yes. Hazard Heights is free to play with a limited number of attempts that refill over time. Hazard Heights Unlimited is a one-time purchase that removes the attempts limit, removes ads, and unlocks offline play. Nothing else is sold; there are no coin packs.
Can I play offline, on a plane?
With Hazard Heights Unlimited, yes. It unlocks offline play; offline runs are unranked and your progress syncs when you reconnect. Free play needs a connection to start a run, because free runs are ranked on the leaderboards.
Are there ads?
No forced ads. Rewarded videos are optional and only play when you choose to watch one for extra attempts. The one-time purchase removes them entirely.
Is it a Tetris game?
It uses tetromino shapes, but nothing else is the same. There are no lines to clear and no grid: pieces obey physics, so placement, balance and weight decide whether the tower stands.
Which phones does it run on?
Android first, with iOS to follow. It is a 2D portrait game and runs comfortably on mid-range phones.
