Gameplay
Before you start a game, you need to choose a map. When first starting, you only have "Golly Grass", the only free map out of your options. The rest of the maps cost gold to unlock. Gold is the premium currency that is affected outside of your games.

Here are the maps currently available:
 * Golly Grass (Free)
 * Block Beach (50 Gold)
 * Rocky Road (100 Gold)
 * Metal Mayhem (150 Gold)
 * Slippery Slope (200 Gold)

When you select a map, you start out with 400 ingame cash, which is used to buy defenses, and 200 lives, which is the threshold you must keep above zero, otherwise you lose the game. You can buy more lives and cash with gold. Unlike cash, you cannot obtain more lives outside of buying them with gold.

The map you must defend on is a cube, in which you can rotate via clicking and dragging the red cube which appears at the bottom right corner of your screen. When you start a round, enemies come out of the start of the path (the green area) and follow the designated path until they reach the exit (the red area). If they reach the red area, you lose lives based on the strength of the enemy.

With your cash, you can buy and place defenses on your cube. There are eight defenses you can buy, from the most cheapest to the most expensive defenses: These defenses harm and destroy enemies in its range. When they destroy an enemy, you gain cash.
 * Mine - $20
 * Turret - $150
 * OctoTower - $225
 * Blizzard - $350
 * Rocket - $500
 * Tripper - $500
 * FireTower - $1100
 * SuperTurret - $3000

The aim of the game is to survive the most rounds possible. Rounds are defined as a wave of enemies in which you must survive or destroy, and each round is defined by the intermission between. For each wave you start, you gain cash.

Gold
Gold is the premium currency that you can gain outside of the games that you play, obtained by completing or losing a game, buying it with Robux, or watching ads on mobile. Its use and function is defined in this official description ingame:

"'Gold is used in the Store tab next to the 'Start Round' button. With it you can buy more lives, cash, and maps! You can obtain gold by dying and collecting gold, buying it, or watching ads.'"

Here are the rates or prices for each quantity of gold to Robux:
 * 10 Gold - 10 Robux (1 Gold : 1 Robux)
 * 50 Gold - 50 Robux (1 Gold : 1 Robux)
 * 100 Gold - 79 Robux (Labeled as "Best Deal" ingame; ~1.26 Gold : 1 Robux)
 * 500 Gold - 399 Robux (~1.25 Gold : 1 Robux)

There are three things you can buy with gold: cash, lives, or maps. The general rate of lives to gold is 10 Lives : 1 Gold. For cash, it's 200 Cash : 1 Gold.
