Retro games were known for their brutal difficulty, often requiring precise controls, memorization, and extreme patience. Unlike modern games with checkpoints, autosaves, and difficulty settings, many classic titles were designed to be unforgiving, forcing players to improve their skills through trial and error. Some games were hard but fair, while others were so punishing that they became infamous for frustrating players worldwide.
Based on player feedback, gaming forums, and difficulty rankings over the years, here are the 20 hardest retro games of all time, ranked from challenging to outright brutal.
20. Punch-Out!! (NES, 1987)
This boxing classic might look simple, but it’s one of the most strategic and reaction-based games ever made. Players had to learn each opponent’s attack patterns and time their dodges perfectly. The final boss, Mike Tyson, remains one of the most difficult bosses in gaming history due to his lightning-fast punches.
19. Shinobi (Arcade, 1987 / Sega Master System, 1988)
This ninja action game required precise jumps, quick attacks, and memorization of enemy patterns. The arcade version was especially brutal, with one-hit deaths and limited continues. Later versions on consoles were slightly easier but still extremely punishing.
18. Fester’s Quest (NES, 1989)
This Addams Family-themed game was notorious for its punishing difficulty. Players had to navigate maze-like levels, dealing with respawning enemies, limited ammunition, and unfair enemy placements. To make things worse, dying sent you all the way back to the start.
17. Contra (NES, 1987)
One of the hardest run-and-gun games ever made, Contra was famous for its one-hit deaths, endless enemy waves, and precision platforming. Without the Konami Code (which granted 30 lives), very few players could complete this game.
16. Kid Chameleon (Sega Genesis, 1992)
With over 100 levels and no passwords or saves, Kid Chameleon was a marathon of a platformer that required insane endurance. The game was filled with hidden traps, blind jumps, and enemy ambushes, making it one of the hardest platformers of the 16-bit era.
15. Castlevania (NES, 1986)
This gothic action-platformer had tight jumps, unpredictable enemy patterns, and stiff movement mechanics, making every level a test of patience and precision. Death and Dracula, the final bosses, are still considered some of the toughest fights in gaming history.
14. Mega Man (NES, 1987)
While later Mega Man games improved the balance, the first game in the series was notoriously unforgiving. Players had to deal with brutal enemy placement, tricky platforming, and frustrating knockback mechanics. Ice Man’s and Yellow Devil’s levels were especially painful.
13. Silver Surfer (NES, 1990)
This side-scrolling shooter had an absurd difficulty curve, mainly because everything could kill you in one hit. The game had tight spaces filled with enemies, punishing level design, and awkward controls, making it one of the most frustrating shooters ever made.
12. Ghosts ‘n Goblins (Arcade, 1985 / NES, 1986)
One of the most legendary “impossible” games, Ghosts ‘n Goblins is brutal from start to finish. You can only take two hits before dying, enemies appear out of nowhere, and the jump mechanics are incredibly stiff. Worst of all, after beating the game, you’re forced to play through it again to see the true ending.
11. Zelda II: The Adventure of Link (NES, 1987)
Unlike the first Legend of Zelda, this game had RPG-style battles, brutal enemy AI, and limited health recovery. The difficulty spike near the Great Palace is legendary, with enemies that can drain your health in seconds and almost no guidance on where to go.
10. Super Ghouls ‘n Ghosts (SNES, 1991)
A sequel to Ghosts ‘n Goblins, this game kept the brutal difficulty and added even more platforming challenges. The double-jump mechanic was both a blessing and a curse, forcing players to commit to jumps without being able to change direction in mid-air. Like its predecessor, you had to beat it twice to get the true ending.
9. Ninja Gaiden (NES, 1988)
This game is known for its lightning-fast gameplay, relentless enemy respawns, and infamous knockback mechanics. If you got hit near a pit, you were almost guaranteed to die. The final boss gauntlet forced players to fight multiple bosses in a row without continues, making it one of the hardest NES games ever.
8. Battletoads (NES, 1991)
Battletoads is often considered the ultimate “rage-quit” game. The Turbo Tunnel level, infamous for its lightning-fast obstacles, is where most players give up. Co-op mode makes the game even harder because you can accidentally hurt your teammate, leading to even more frustration.
7. The Lion King (Sega Genesis / SNES, 1994)
Despite being marketed as a kid’s game, The Lion King is shockingly difficult. The “Can’t Wait to Be King” level requires near-perfect platforming, and enemy hitboxes are unforgiving. Many players never made it past the first few levels.
6. The Immortal (NES, 1990)
An isometric action-RPG, The Immortal was brutally difficult due to its trial-and-error gameplay. Almost everything in the game could kill you instantly, and enemies were designed to be as unfair as possible.
5. I Wanna Be the Guy (PC, 2007 – Retro-Style)
Although not an actual retro game, I Wanna Be the Guy mimics the brutality of NES and SNES-era difficulty. It deliberately tricks players with instant death traps, unpredictable enemy attacks, and absurdly hard platforming sections. It became a cult classic among hardcore gamers.
4. Takeshi’s Challenge (Famicom, 1986)
Created by Japanese actor Takeshi Kitano, this game was designed to be nearly impossible to complete. It features bizarre, unexplained mechanics, including waiting hours in real-time or solving cryptic puzzles with no hints. Many consider it one of the worst-designed games ever made, but it’s legendary for its challenge.
3. Kaizo Mario (Unlicensed ROM Hack, 2007)
A fan-made Super Mario World mod, Kaizo Mario takes Mario platforming to an extreme level, with hidden traps, pixel-perfect jumps, and troll mechanics. This game became popular among speedrunners but remains one of the most difficult platformers ever created.
2. Contra: Hard Corps (Sega Genesis, 1994)
Unlike Contra on the NES, Hard Corps removed the Konami Code and gave players only three lives to complete the game. The fast enemy AI, nonstop explosions, and massive bosses made it one of the hardest run-and-gun games ever made.
1. Touhou Project Series (PC, 1997–Present)
The Touhou games are bullet hell shooters, where the screen is covered in thousands of projectiles. Players must dodge pixel-perfect patterns with almost no room for error. These games have a dedicated competitive scene, but even casual players struggle to complete them on normal difficulty.
