The official description says to fight endless waves and see how many you can survive. The only official difficulty rule is that the longer you survive, the harder the Verities become. There is no published multiplier, HP curve, threshold, or final wave.
The loop
Day, or the pause you control, is for walls, turrets, and coins. The raid is the night attack. In footage, players press Start raid, sometimes beginning a new raid at a chosen wave such as wave 25. Building locks while the raid is active. Ending the raid brings building and gun purchases back. Guides also describe waves as automatic night attacks. No source fully explains how the clock and the manual raid button fit together. The stable parts are numbered waves, a lock on building, and a break after the last Verity falls.
A wave is survived when every Verity in it is defeated. The break length is not documented, so use it immediately. There is no confirmed payout for every cleared wave. The only wave-related lump sum on tape is 5,000 coins after a wave-10 boss in one session.
What the screen shows
| Readout | Meaning |
|---|---|
| Wave number | Starts at 1 and rises as waves clear. Creators have narrated 1, 8, 10, 23, 90, and 91. |
| Enemies remaining | The wave ends when the last Verity falls. |
| Coins on kills | Income during the fight, spent in the break. |
| Boss or mini-boss callouts | Heavier enemies appear, but not on one confirmed schedule. |
| Top wave, top kills, top coins | One video showed a top wave of 700. Personal best or leaderboard is unconfirmed. It is not a cap. |
Boss timing does not line up. One run met a mini-boss around waves 4 to 5. Others met large Verities at 10, 15, and 20. Do not plan a route around a single schedule. Public data has not confirmed an official Boss category. Narrators use "boss" for large threats.
What actually gets harder
Durability, group size, and new behavior account for the pressure. Early waves are small and low durability. Middle waves arrive in clusters. Late waves concentrate on weak walls. Later footage adds weapons, shields, explosives, diggers, side and rear attacks, and faster movement.
These wave numbers are single sessions, not breakpoints:
| Wave on the counter | What that session showed |
|---|---|
| 10 | A very large Verity destroyed several turrets. From wave 11 the narrator started taking damage. |
| 14 | Verities carrying weapons in one run. Another run was hit from behind around this stage. |
| 15 to 16 | Guns and shields, fast ninja-like variants, side attacks, and 13 enemies at once in separate sessions. |
| 18 | 24 or more Verities at once, and explosive Verities breaking defenses. |
| 25 to 91 | A giant wave opened wave 25. At wave 91 a bomb Verity chased the player. |
Typical footage ended between waves 8 and 26. One heavily invested run reached the wave 90s after high-HP blocks, a large coin pile, and rebirths. Those are showcases, not a normal target.
Compare your own early wave with your latest one. Note which walls were hit, how many enemies arrived together, and whether diggers, side attacks, or explosives appeared. Reinforce that side. There is no formula to copy.
