Rantadi: Random Tower Defense

Summon heroes, merge them and hold the path. Between runs, level up your heroes, collect relics and take on harder difficulties.
Rantadi is a random tower defense game played on a single portrait screen.
Who you summon is random; where you place them and when you merge is up to you, so every run plays out differently.

■ Summon and merge
- Pick an empty slot to summon there, or let a hero appear in any empty slot
- Merge two identical heroes to get a higher-tier hero in the slot you tapped
- 40 heroes across 8 lines and tiers 1 to 5, including Bonnie the skeleton crossbowman, Ria the elf archer, Ruby the winged demon and Kai the fire mage
- Each line has its own job: anti-air, area damage, slowing enemies, supporting allies

■ Three battlefields and three difficulties
- Forest: 40 waves, a good place to start
- Desert: 30 waves on a zigzag road for a quicker run
- Snowfield: 40 waves of armored enemies and a narrow choke point
- Every stage has Normal, Hard and Hell. Clearing one difficulty unlocks the next on that stage
- Hard adds elite waves and Hell adds mutant bosses. Enemies get tougher and coin rewards grow with each step
- Every stage has its own road, four bosses, missions and economy

■ Level up your heroes
- Spend coins to raise each of the 8 hero lines from level 1 to level 20
- The level cap opens in steps of 5, 10, 15 and 20 as you clear higher difficulties
- A level you earn applies to every run in which that line appears

■ 12 relics
- Twelve relics that bend the rules, such as Vault, Ticket Piggy, Favorite Charm, Merge Insurance, Lucky Summon, Frost Ward and Rampart
- You start with 1 relic slot, get a 2nd by clearing Hard and a 3rd by clearing Hell
- Each difficulty you clear on a stage rewards a pick of 1 relic out of 3. Finding the same relic again levels it up
- Choose which relics to equip before each run

■ Mutant bosses
- On set waves of Hell, the boss shows up as a mutant
- It carries one trait: shield, regeneration, cold immunity or splitting. The trait is shown before the run begins
- Building your heroes and relics around that trait is the key to the fight

■ Daily missions and check-in
- Three daily missions open each day. Finish all three to get a chest with coins, gems and a chance at a relic
- A 7-day check-in reward is included. If you miss a day, it is not skipped and picks up the next time you play
- Missions can be done within a single run, and rewards are collected automatically on the result screen

■ Play at your own pace
- 2x speed is available from the start
- Close the app mid-run and it resumes right where you left off
- Playable without an internet connection (ads, purchases and cloud save need a connection)
- Signing in is optional. Connect Google Play Games if you want your progress saved in the cloud
- The codex and records keep the heroes and enemies you met and your past runs

■ Good to know
- A banner ad is shown at the bottom of the screen
- Rewarded ads are always optional. They can double a run's coin reward, continue after a defeat (once per run), double the daily chest or reroll the daily chest when it gives no relic
- In-app purchases: Remove Ads, Starter Pack, 2x Without Ads and three gem packs
- Gems are spent only on fixed items such as unlocking relic slots. There are no paid random draws
- Available in English and Korean
