Cameraman Tower Defense Gems: How to Get Them & Spider Crate Odds

This guide covers Update 3 (October 2026) gem income and Exclusive Spider Crate spending. For Robux Scientist crates and pack prices, stay on shop and crates. For lobby Coins and in-match cash, see coins and economy. TV Spider stats and all units drop tables live on their own pages.

What are gems in Cameraman Tower Defense?

Gems are the blue-diamond lobby currency added in Update 3. Lobby footage summarized on our update log shows Gems + Spiders Update banners and gem-priced Shop rows—in every capture we reviewed, the clearest gem sink is the Exclusive Spider Crate, not tower placement cash and not win Coins.

MeddysonTD’s inventory clips show the gem counter beside Coins on the bottom HUD (528s). Opening many crates fills Units → Inventory toward the 500 slot cap seen at 68/500 after his bulk Spider pulls (270s).

How do you get gems for free?

Vaulted Values X says gems come from quests that appear after 20 wins, pay five gems per quest, and show four quests at once—examples include beating Hard or clearing a mode with only one hotbar slot (MhtBS1AEEwo ~5:46). Vaulted Values X also says a full board is worth 20 gems when all four finish.

MeddysonTD says gems are “almost non-existent” in the economy right now and that quests “seem” to give five gems each—his auto-caption literally says “five stars per quest” (zHfmcl5zdBo ~10:02). That aligns with Vaulted Values X on payout size only; he does not confirm the 20-win unlock or four-task board in that clip.

Screenshot source: MeddysonTD on YouTube (https://www.youtube.com/watch?v=zHfmcl5zdBo&t=528s). Frame shows 326 Coins, 0 gems, and 25/500 Items capacity—not a quest payout screen.

The same 20+ Wins Quests label appears on MeddysonTD’s shop lobby capture (Sv4SgTBFMWU ~10s), which supports the unlock gate but not per-quest gem amounts.

What we do not know (unverified): average matches per quest, daily refresh rules, code rewards in gems, or any hidden quest reroll costs. Aggregator sites sometimes list gem bundles or code payouts—we do not treat those as verified for this game.

Can you buy gems with Robux?

MeddysonTD says he bought gems with Robux near the end of his TV Spider video and opened 30+ more Spider attempts (zHfmcl5zdBo ~8:01). In his TV Woman video he says he is holding 4,000 gems before more Spider Crate pulls (BvvGAZLRC2U ~1:01), and the lobby HUD at ~1:28 reads 4,000 next to his coins (same frame as on our all units guide). Nothing on screen says where those gems came from.

We did not read a live Robux → gems price in any frame we kept, so this page lists no Robux gem prices. A few third-party stat sites quote gem bundle prices; with no on-screen proof, we left them out.

What does the Spider Crate cost and what are the odds?

The Exclusive Spider Crate price board in early-October Shop footage lists:

Vaulted Values X says there is no discount for tens unlike the coin basic crate (MhtBS1AEEwo ~6:17).

Drop rows on the same board read:

MeddysonTD says the Buy 10 shop control was disabled while Buy 3 still worked (zHfmcl5zdBo ~4:31). When opening stored crates, a popup still offered Open 1 and Open 10 (600s)—shop purchase versus inventory open may differ; we only have his one session.

How many gems does a Spider Crate prize really cost?

Assume independent pulls at the posted rates and 100 gems per single open.

Quest conversion (Vaulted Values X narration, our arithmetic):

Camera Spider (9.8%): probability of at least one in n pulls = 1 − (0.902)^n (our arithmetic):

TV Spider (0.2%): 1 − (0.998)^n (our arithmetic; MeddysonTD’s voiceover rounds similar thresholds):

MeddysonTD says roughly 347 pulls for 50%, above 1,000 for 90%, and above 2,300 for near-guarantee (zHfmcl5zdBo ~9:02). Our arithmetic lands at 347, 1151, and 2301 pulls for 50%, 90%, and 99%—same story, slightly different rounding than his “2.3 thousand” phrasing.

Vaulted Values X says TV Spider’s tooltip 40 range is walk range, while attack range only reaches 20 (MhtBS1AEEwo ~6:47). MeddysonTD’s TV Spider card frame shows Walk Range 15→40 and Range 11→20 separately (58s).

Is the Spider Crate worth your gems?

Vaulted Values X says to save gems for Camera Spider, treat TV Spider as a lottery, and only chase it if you accept losing the gem stack (MhtBS1AEEwo ~9:24). On the tier list they call TV Spider strongest on paper but “a trade, not a pull” for most players because of the 50,000-gem average (lRtpetkMJZs ~0:30).

MeddysonTD opened 30 stored Spider crates in one montage without a TV Spider (zHfmcl5zdBo ~8:01). Our arithmetic: (0.998)^30 ≈ 94.2% chance of zero TV Spiders in 30 independent pulls—unlucky, but normal at 0.2%.

Screenshot source: MeddysonTD on YouTube (https://www.youtube.com/watch?v=zHfmcl5zdBo&t=270s). The Camera Spider tooltip reads DPS 100→3500, Walk Range 15→35, and Range 10→20, so the roughly 3,500 DPS figure above is a card readout as well as narration.

Editorial suggestion (untested): If you are free-to-play, finish the beginner guide win loop, treat Vaulted Values X’s quest route as the main documented gem faucet, and stop at Camera Spider odds unless you enjoy gambling. Whales mirroring MeddysonTD should still budget inventory space—500 units adds up fast when 90% pulls are Speaker Spiders.
