OnceWorld is a simple and casual 2D solo-play RPG. Relive the charm of classic MMOs from the good old days — now reimagined for mobile with easy controls and deep progression! Level up, reincarnate, raise pets, awaken equipment, collect materials, and battle in the arena — all in one nostalgic adventure. It’s an RPG that brings the essence of those mid-2000s MMORPGs to your smartphone, blending nostalgia with modern convenience. ▼ Stat Distribution Distribute points into seven basic stats to develop your character. Points are earned as your hero levels up. To reset your distribution, you’ll need a special item. Stat meanings: VIT – Increases HP SPD – Attack speed & number of strikes ATK – Physical attack power INT – Magic attack power & SP capacity DEF – Mainly physical defense power M.DEF – Mainly magical defense power LUK – Evasion & Physical Critical ▼ Weapons & Armor Equip one weapon and five armor pieces. Wearing all five pieces of a matching set grants a set bonus. Use the heart icon at the top-left to toggle your favorite gear display. ▼ Equipment Enhancement Use materials obtained during your adventures to enhance your gear. Each enhancement attempt has a success rate — failure consumes the materials, but the item itself will never break. Some special items can increase success rates. ▼ Accessories Accessories grant special effects when equipped. Defeating enemies while an accessory is equipped will level it up, enhancing its effects over time. ▼ Magic Spend SP to cast powerful spells. Magic attacks cannot be evaded and there are no critical hits. Certain rare materials may further amplify spell power. ▼ Monsters & Pets By carrying a special material, you’ll gain the ability to capture monsters. Captured monsters become pets that grow stronger as they fight alongside you. Some monsters learn skills as they level up. These skills can activate even without being summoned, as long as the monster is accompanying you. Pet switching can only be done at the Pet Keeper in your hometown. Feeding specific materials will raise a pet’s stats. ▼ Monster Encyclopedia Once defeated, monsters are added to the encyclopedia where their stats can be viewed. Captured monsters will display a “Caught” mark. ▼ Materials Materials are divided into three categories: Normal Materials  Used for equipment enhancement and trading. Effect Materials  Provide passive bonuses simply by owning them.  Have a smaller carrying limit. Key Items  Only one can be held.  Cannot be dropped or sold. ▼ Items Items that grant various benefits during adventures. You can assign them to shortcut slots for quick use in the field. Swap registered items using the arrow icon beside the item list. ▼ Reincarnation When your hero reaches the level cap, you can reincarnate. Reincarnation resets your level but increases your level cap and available stat points, allowing for further growth. ▼ Abyss Corridor A ranked mode that can be played a limited number of times per day. Clear each floor by defeating all monsters as fast as possible — faster times rank higher. Treasure chests appear as rewards on each floor. Only Save Slot 1 is eligible for ranking participation. ▼ Arena Watch monster battles. Watch monster battles held several times a day. Choose the strongest team from three teams and watch the battle. Earn Arena Coins if your favorite team wins. Try exchanging them for valuable materials at the Arena Shop. ▼ About the Kin-Slayer Rite ▼ The Kin-Slayer Rite is a ceremony in which the target pet’s kin-bond, level, and accumulated experience are all returned to zero in exchange for enhancing its base stats. A monster that undergoes this rite will gain experience at a slower rate thereafter.

Verdict

The call

The clearest difference is rating: OnceWorld at 4.9 against Hack&Slash Frontier's 4.2. OnceWorld also leads on update cadence (every 2 days vs weekly) and ratings volume (128 vs 9). Hack&Slash Frontier's advantage is review sentiment (72% vs 59%) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Hack&Slash Frontier sells 4 one-off in-app purchases and OnceWorld sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

OnceWorld holds the better App Store score, 4.9 against 4.2. That said, the two scores are not equally well evidenced: OnceWorld has 128 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 72% of Hack&Slash Frontier's written reviews are positive against 59% of OnceWorld's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Hack&Slash Frontier ships an update weekly, OnceWorld every 2 days. Both last shipped on September 28, 2026.
