100 Floors Survival Guide: 7 Tips to Reach Floor 100

October 4, 2026 · 4 min read

100 Floors is easy to understand and brutally hard to master. The zombies get faster, the doors feel slower, and somewhere around floor 30 most players hit a wall. Here is how to push through to floor 100.

1. Learn the audio cues

Zombies announce themselves before they appear. Play with sound on — those few tenths of a second of warning are the difference between a clean shut and a lost life.

2. Do not slam both doors at once

Panic-slamming feels safe but leaves you blind. Shut only the door under threat and keep your eyes on the other side. Calm players survive; panicking players do not.

3. Coins are worth the risk — sometimes

To grab a coin you must keep a door open near a zombie. Worth it on slow early floors; suicidal past floor 40. Spend coins in the shop on bombs — the best investment in the game.

4. Save bombs for swarms and The Jin

From floor 11 you get 2 bombs per floor. From floor 21, The Jin smashes through shut doors and bombs are the reliable answer. Never waste your last bomb showing off.

5. Prioritize the shield power-up

Shield, slow-mo, auto-slam, pistol — all good, but shield is king before boss floors. One free mistake on a boss floor is often the run-saver.

6. Use checkpoints smartly

Checkpoints unlock every 10 floors from floor 11. If you are learning a new enemy pattern, practice from a checkpoint instead of grinding from floor 1 every time.

7. Chase combos, not kills

The combo multiplier (up to x5) rewards clean streaks. Smooth, deliberate door work outscores frantic slamming every time.

Floor 100 is waiting. Shut those doors!
