Alliance Tower Defense Coin & Crate Farm Estimator
Enter your own Coins-per-clear, run time, and success rate below — the estimator projects a session from your measured numbers, not from anyone's claimed rate.
Measure first, then project
Every farming projection is only as honest as its inputs, so this page starts from your own records: run five clears of your farm mode, note the Coins per clear, the minutes per run, and how often you actually win. The estimator multiplies that into a session plan. For most accounts the answer is the solo Easy City loop (100 Coins per short, unfailable clear), upgraded to Medium (275) or Hard (500) the moment those stop failing. Crates are the parallel track — Insane prints Scientist Crates, the hourly Piñata prints Party Crates, and Crazy funds the Spin Wheel.
Estimate a session from your observations
Matches earn Coins. Enter what you observe in your current mode and loadout; this does not promise a universal rate or a Crate drop rule.
Crate track
Crate odds and where they drop
Community-documented drop tables, checked 2026-10-15. Crates are separate from the Summon pool — Coins cannot buy them.
Party Crate
Party Camera Man 60%, Jester Speaker Man 39.75%, Party Titan TV Man 0.25%. Obtained from the hourly Piñata (1–3 crates per kill) and Party Global Quests.

The Piñata and quest timers
Timed events that pay crates without a full match.
Piñata (hourly)
Spawns 30 minutes after the quest refresh. The whole server gets Bats to hit it; its HP scales with the number of players. Killing it pays 1–3 Party Crates plus Coins. The Golden Bat gamepass doubles your Piñata damage.

Global Quests
Server-wide quests on hourly, daily, and weekly timers, introduced with the Party Event and refreshed with a new set in late August. Party Global Quests also pay Party Crates.

Coins that earn themselves
Coins
Earned from modes (see the reward table), from selling unwanted units, from the Group Rewards chest (150 Coins per 24 hours — join the MrUpTime's Games group to claim), and from the VIP chest.
Tickets
Earned by beating Crazy mode (1 per clear) or bought with Robux. Spent on the Spin Wheel in the right corner of the lobby, which has 7 prizes including the DJ Speaker Man at 5%.
AFK Area
An idle zone in the lobby paying 2 Coins per minute, added August 7. The only documented AFK Coin source — meaningful as a topping-up mechanism, not a farming strategy.
FAQ
Farming questions
How many Coins per hour can I farm?
It depends on your loop speed, which is why the estimator uses your own numbers. Five measured Easy City clears give you a personal Coins-per-hour figure; solo Easy loops are the community staple because they never fail. A first Insane clear pays 850 Coins plus a crate but runs 20+ minutes and can fail.
How do I get Scientist Crates fast?
Beat Insane mode — each clear pays 1 Scientist Crate (850 Coins alongside). At 95%, most crates give the Scientist Camera Man economy unit; 4.8% is Large Scientist and 0.2% is the Engineer.
When does the Piñata spawn?
Hourly, 30 minutes after the quest refresh. The whole server gets Bats, its HP scales with server population, and a kill pays 1–3 Party Crates plus Coins. The Golden Bat gamepass (39 Robux) doubles your Piñata damage.
What are Tickets for, again?
The Spin Wheel in the lobby's right corner. Crazy mode pays 1 Ticket per clear; the wheel has 7 prizes including DJ Speaker Man at 5%. Tickets can also be bought with Robux.
Step-by-step: measure, then project
- 1. Run the easiest mode you cannot fail three times and note the Coin payout of each clear.
- 2. Time a full loop — queue, clear, reward screen — to get a realistic Coins-per-hour figure.
- 3. Feed your goal (crate price or 850-Coin 10-pull) into the estimator and read the sessions needed.
- 4. Re-measure after any update: rebalances and X2 windows change the math overnight.
If you're stuck
If your measured rate lands far below the plan, check the mode multiplier and wave count first — most shortfalls are a wrong map or an unclaimed Group Rewards chest, not a broken strategy.
Common mistakes
Trusting an unverified per-hour claim from a video without measuring your own runs, and farming Insane for Coins before the Scientist Crate economy that makes Insane worth running.
