Modes & Waves

Four ways to play. Classic and Random share one 25-wave script and differ only in where the enemies come from; Endless continues past it; New Game+ replays the whole thing harder.

Classic

Entrances sit on the top row in fixed, evenly spread positions — you choose how many, and that choice is the difficulty setting.

Entrances	Positions (column)	Difficulty
1	5	Easy
2	0, 10	Normal
3	0, 5, 10	Hard
4	0, 3, 7, 10	Impossible

The board runs through all 5 biomes, one per five waves, and the run ends in victory after wave 25 — or continues into Endless if you choose.

Biome	Waves	Character
🌿 Plains	1–5	The battle begins on open grasslands.
🏜️ Desert	6–10	The battlefield shifts to scorching desert sands.
❄️ Tundra	11–15	A frozen tundra stretches before you. The cold bites deep.
🌲 Forest	16–20	Dense forest canopy closes in around the battlefield.
🏔️ Mountains	21–25	Rocky mountain peaks tower above. The final stand awaits.

All 25 waves

Wave n allows up to n÷5 rounded up enemy types, so compositions widen as the run goes on. The HP column is the multiplier applied to every enemy's base stat block that wave.

Wave	Biome	Composition	Count	Spawn gap	HP
1	🌿 Plains	Grunt×8	8	0.8s	×1
2	🌿 Plains	Grunt×14	14	0.65s	×1.22

25 BOSS	🏔️ Mountains	Boss×5 Runner×18 Tank×14 Flyer×14 Brute×7	58	0.25s	×6.28

From wave 21 onward, spawns rotate round-robin across every entrance rather than picking one — with 4 entrances that is four simultaneous streams.

Random

Identical waves, different geography. Entrances are placed randomly instead of on the top row, at least 5 cells apart (Manhattan distance) and never in the bottom 6 rows. A cave that spawns halfway down the board gives you far less maze to work with, and you cannot plan a layout in advance. Random keeps its own leaderboard.

Endless

Past wave 25 the game generates waves procedurally. Boss count climbs by one per wave to a ceiling of 10, every other group scales by 30% per wave past the end, and the spawn gap tightens by 0.01s per wave down to a 0.1s floor.

Wave	Composition	Count	Spawn gap	HP
26	Boss×4 Tank×18 Brute×9 Runner×23 Flyer×18	72	0.24s	×6.5
27	Boss×5 Tank×22 Brute×11 Runner×28 Flyer×22	88	0.23s	×6.72
28	Boss×6 Tank×26 Brute×13 Runner×34 Flyer×26	105	0.22s	×6.94
29	Boss×7 Tank×30 Brute×15 Runner×39 Flyer×30	121	0.21s	×7.16
30	Boss×8 Tank×35 Brute×17 Runner×45 Flyer×35	140	0.2s	×7.38
31	Boss×9 Tank×39 Brute×19 Runner×50 Flyer×39	156	0.19s	×7.6
32	Boss×10 Tank×43 Brute×21 Runner×55 Flyer×43	172	0.18s	×7.82
33	Boss×10 Tank×47 Brute×23 Runner×61 Flyer×47	188	0.17s	×8.04
34	Boss×10 Tank×51 Brute×25 Runner×66 Flyer×51	203	0.16s	×8.26
35	Boss×10 Tank×56 Brute×28 Runner×72 Flyer×56	222	0.15s	×8.48

Shown here to wave 35; the formula continues indefinitely.

New Game+

Offered after a victory. Each NG+ level multiplies enemy HP by 1 + 0.5 × N and adds 10g to your starting gold, with freshly randomised entrances. The wave script is unchanged — only the arithmetic moves.

NG+ level	Enemy HP	Starting gold
NG+1	×1.5	30g
NG+2	×2	40g
NG+3	×2.5	50g
NG+4	×3	60g
NG+5	×3.5	70g

NG+ runs are scored on their own leaderboard section.

Campaign

The campaign is a separate 25-level progression with hand-built maps, per-level arsenals and star ratings — it does not use the wave script above. See all 25 levels →
