Learn how you lose one only on a fail, why tutorials are free, how hearts refill, and what to do when out. Hearts are your play energy in Hepta. They keep things relaxed: you can settle into a level, take your time, and try a tricky board more than once without pressure. ## What hearts are You start with a set number of **hearts**, shown as a small badge on the Home screen. Each heart is simply permission to keep playing. Because Hepta is a calm merge puzzle with no ads, hearts are the only thing pacing your play, and they're designed to stay out of your way. Hepta Home screen showing the current level, the play button, and the hearts badge ## You only lose a heart when you fail A heart is spent **only when you fail a level** — never when you win. Clear a board and your hearts stay exactly as they were, no matter how many moves it took. Winning never costs a heart. You can keep clearing levels back to back without spending anything. Hearts come into play only when a level doesn't work out. This is part of Hepta being fair and player-friendly: the game is easy to learn and hard to master, so a level that takes a few attempts is normal, and succeeding is always free. ## Tutorial levels are free While you're learning, **tutorial levels never cost a heart**. You can practise the basics — merging matching pieces, watching the ripple, building the target — as many times as you like. Failing a tutorial level won't reduce your hearts, so it's a safe place to get comfortable before the full set of levels. ## Hearts refill over time Hearts **refill over time** while you're away. Step away for a bit and you'll come back to more hearts than you left with, ready to pick up where you stopped. There's nothing to tap or claim — refilling simply happens in the background as time passes. ## Out of hearts? If you run out, you have two calm options: Hearts refill over time on their own. Take a break and check back soon. Lift the heart limit for a while with an optional Unlimited pass. Either way, your progress, best move counts, and stars are always saved — running out of hearts never sets you back. ## Related Play heart-free for a while with Hepta's fair, optional passes.
