| Symbol | What it does |
| ♦ ♣ ♥ ♠ | Low symbols (aces): no pay, their wins start cascades |
| Pistol | 6 rounds × 2 damage at the nearest zombie (10% crit ×2) |
| Shotgun | 4 blasts × 3 damage to the target and the 3 cells behind it |
| Rifle | 10 rounds × 2 damage (8% crit) |
| Sniper | 2 shots × 12 damage at the highest-level monster; goes through shields and armour and also hits the monster behind it (15% crit) |
| Minigun | 20 rounds × 3 damage (5% crit) |
| RPG | 2 rockets × 20 damage to the target and 8 to the 3×3 around; ignores helmet armour |
| Wild | Ammo Box — substitutes all paying symbols, +1 round to the weapon win |
| Double Ammo | +1 point on the skill panel (max 3): doubles the rounds of one weapon win |
| Explosive | +1 point (max 3): every round of one weapon win kills in one hit (not the boss) |
| Flash Grenade | Goes off at once — zombies don't move this turn. Extra grenades wait on the panel (max 3) and go off at the start of the next spins. |
| Turret | Arms the sentry turret next to the hero for 3 spins (up to 6): every spin, after the cascades, it fires 6 rounds × 3 damage at the nearest monsters |

| Runner | 56 | 2 cells forward |
| Splitter | 116 | splits into two Walkers when killed |
| Door | 104 + 78 door | the door soaks damage first (the sniper goes through it); once it breaks the zombie is angry and walks 2 cells |

| Boss: Caller | 2600 | 1 row every 2 spins; every 2 spins screams a row of 3–5 zombies onto the top of the road |
| Every boss: 5 HP segments; killing it pays the max win. The kind is random (Brute 40%, Tank 30%, Caller 30%). |
