What is the same?
Players who played Grow Castle first say the core is nearly identical. One called it an almost 1:1 copy with slightly more features. A forum thread lists the shared parts:
- A castle on the left with heroes standing in its windows, attacking automatically.
- Towers placed in front of the castle, and enemies marching in from the right.
- Endless waves with a boss every few waves, gold from kills, and upgrades between fights.
- Talent points, and portals to separate boss fights.
Other reviewers compare it to Storm the House and Kingdom Rush, but Grow Castle is the name that comes up most.
What does Legend of Defenders add?
- A gear game: Rift Raid bosses drop equipment, and the Blacksmith enchants and rerolls it. See equipment and stats.
- Demon Lord Tower: floors whose element weakness changes every 20 floors. See Demon Lord Tower.
- Elements and team building: Fire, Ice, Poison, Thunder and Physical teams, captains who walk the field, and a large talent tree. See team comps and the tier list.
- Recruiting without a shop: the Tavern gacha runs on diamonds earned from the Mine and quests. See diamonds, Tavern and Mine.
- PC comforts: a Boss Key, auto battle that also aims the cannon, and progress while you are away. See settings and controls.
What it does not have: no leaderboards and no guilds. The developer says leaderboards would fill up with cheaters. Players who liked Grow Castle’s rankings miss them.
Can you play Grow Castle on PC?
Yes. Grow Castle is not on Steam, but its Google Play listing shows it as available on Windows through Google Play Games. That is the same free game with the same ads and in-app purchases, run on a PC. Emulators such as BlueStacks are the other route.
If what you want is a Grow Castle-style game made for PC, without ads or a shop, that is the gap Legend of Defenders fills. Saves from the demo carried over to the full game. See saves, price and platforms.
Which one should you play?
- Pick Legend of Defenders if you want to pay once and never see an ad or a shop, and you like gear and team building on top of idling.
- Pick Grow Castle if you want to play free, on your phone as well, or care about rankings against other players.
- Know the catch: several reviewers say Legend of Defenders runs out of new things after the first few hours, and the rest is idling and upgrading. The developer says seeing everything takes around 500 hours. New players can start with the beginner guide.
