The Coin Launcher (コインシューター, Coin Shooter) is a trophy-snagging minigame in Super Smash Bros. Brawl. It acts as a replacement for the Lottery feature of Super Smash Bros. Melee, and it itself was replaced by Trophy Rush in Super Smash Bros. 4.
The Coin Launcher, as the name implies, is a machine that uses coins as projectiles. Using the Launcher, coins are shot at trophies to obtain them, with each trophy requiring 2—4 coins to be captured. Players must press the fire button each time they wish to shoot a coin, though the button can be held briefly and released to launch a a coin at a higher speed.
While attempting to shoot at trophies or waiting for more trophies to appear, enemies can also appear in the mode. Enemies appear in waves, and require one coin to destroy. Destroying entire waves of enemies increases the spawn rates of rare trophies, grants a small amount of extra coins from 10 to 50, and can provide the player some stickers. Destroying individual enemies also fills a gauge in the mode, which is displayed below the player's coin supply. Upon filling all ten squares, the Launcher will gain a temporary boost to firing speed, and, depending on timing, two or three trophies may automatically appear. The gauge empties after some time, though successive increases in the gauge gradually increase the rate at which uncollected trophies appear.
Missiles, which require 2 coins to destroy, can also appear at random in the mode, either by themselves, as part of enemy waves, or as massive swarms that attempt to overwhelm the player. The swarms appear at complete random but only require one coin each to destroy. Destroying missiles can grant bonuses, such as more coins or increasing the chance of finding a rare trophy; getting hit by one, however, depletes the gauge and deducts 20 coins.
The counters for trophies and stickers do not display numbers over 99, but it is possible to earn more than 99 trophies or stickers at one time.
There are six types of enemies that may appear (note that the naming is unofficial).
Pits may also appear at intervals, usually in conjunction with Plunks. Coins will be wasted if they fall into a pit, but charging a coin can potentially allow it to "jump" across the corners of these pits.
