SpongeBob Tower Defense endless mode rewards include Gems upon elimination, wave-scaled Player XP, Season Pass XP, Unit Food, and milestone payouts from Endless Quests. Running Endless Mode also counts toward passive 30-minute crate timers and Faction Points.
Official patch notes and player testing establish the exact reward systems, scaling mechanics, and farming output for Endless Mode in this Roblox game developed by Krabby Krew / Wonder Works Studio.
Confirmed Endless Mode Rewards
Endless Mode rewards scale based on the number of waves survived and total match duration. While early builds did not grant experience for running Endless, subsequent game updates overhauled the payout structure to reward long-session play.
| Reward Type | Source / Scaling Mechanic | Verification Source |
|---|---|---|
| Gems | Awarded at the end screen based on total waves survived | Player testing (Wave 150 benchmark) |
| Player XP | Scaled dynamically based on waves completed | Official Update 5 Patch Notes |
| Season Pass XP | Scaled dynamically based on waves completed | Official Update 5 Patch Notes |
| Unit Food | Awarded upon session completion based on waves cleared | Official Update 5 Patch Notes |
| Endless Quest Rewards | Higher wave milestones unlock quest-specific payouts | Official Update 3 Patch Notes |
| Faction Points | Earned by clearing waves during active Faction seasons | Official Update 14 Patch Notes |
| Event Crates (e.g., Sand Crates) | Earned at a rate of 1 crate per 30 minutes of match time (stacks on return to lobby) | Official Update 26 Patch Notes |
Gem Yields and the Wave 150 Benchmark
Gems serve as the primary currency payout from Endless Mode. In a recorded match running auto-skip and 2x game speed, clearing up to Wave 150 took 44 minutes and awarded 648 Gems on defeat.
- Base Session (Wave 150): 648 Gems across 44 minutes of active play.
- Standard 24-Hour Continuous Projection: Roughly 21,000 Gems (assuming ~32 runs per day without boosters).
- With 2x Gem Boost Active: 1,296 Gems per 44-minute run, totaling over 40,000 Gems in a continuous 24-hour cycle.
Endless runs can be pushed well past Wave 150 depending on team placement, traits, and damage output, but this 44-minute wave mark represents a standard reference point for players assessing their Gem return over time.
Experience and Unit Food Scaling
In early versions of the game, players reported that Endless Mode awarded 0 XP, making Raids and Story chapters the only viable experience farms. However, Update 5 explicitly overhauled Endless Mode by adding:
- Player XP based on total waves completed.
- Season Pass XP scaled to match depth.
- Unit Food drops scaling with higher round thresholds.
Because food drop items and player experience require survivability, deeper runs maximize your payout per game. Players seeking extra efficiency can stack gamepasses such as the 2x Player XP pass or the 2x/4x Food Drops passes to amplify payouts collected at the end of each session.
Stacking Timed Crates During Endless Runs
Endless Mode allows players to rack up playtime-dependent crate rewards without returning to the lobby every few minutes. Under the Sand Crate system introduced in Update 26, crates accumulate passively during matches:
- Players earn 1 crate for every 30 minutes spent in any active game mode.
- Crates stack during prolonged Endless runs. For example, a 2-hour Endless session allows a player to claim 4 accumulated crates immediately upon returning to the lobby.
- Unlike active gameplay in Endless Mode, idle AFK area mode was specifically excluded from earning Sand Crates.
Endless Mode Quests and Faction Progress
Beyond match-end rewards, surviving in Endless Mode progresses several meta systems:
- Endless Quests: Added in Update 3, these quests reward players with extra items and currencies when they hit specified wave thresholds.
- Faction Points: Introduced in Update 14, players who have joined a Faction generate Faction Points by participating in Endless Mode, which can then be spent at the Faction Shop.
- Map Variants: Later expansions, such as Update 17, introduced dedicated Endless modes for new story environments like Rock Bottom, expanding the stages available for wave grinding.

Yes. Although original versions awarded 0 XP, Update 5 introduced Player XP, Season Pass XP, and Unit Food rewards that scale based on the total number of waves completed.
How many Gems do you get for reaching Wave 150?
In recorded gameplay tests using 2x game speed and auto-skip, reaching Wave 150 in roughly 44 minutes awarded 648 Gems without active boosters.
Do passive crate timers work while inside Endless Mode?
Yes. Game systems that grant rewards based on playtime, such as the Sand Crate feature introduced in Update 26 (1 crate per 30 minutes), stack throughout an Endless run and can be collected when you return to the lobby.
