Basics

Candy Kingdom Defense CodesWorking codes: RELEASE, HALLOWEENSOON, THANKSFOR200LIKES, THANKSFOR100CCU, ALGEBRAIC and MATHEMATICAL — together 4,600 gems, 63 Trait Crystals, 5 Juice and 3 XP Candy. Redeem them with Jake at Jake's Code Corner in the Tree Fort (Areas button → Jake's Code Corner). No codes have expired yet.
Beginner Guide and How to Get Gems▶ VideoPick Finn or Jake (Jake → Alien Jake is the easiest early evolution), redeem the 6 codes (4,600 gems), log in daily (7,000 gems per 7-day streak), claim 1,000 gems every 5 player levels at Finn's Campsite, and farm Candy Road (50 gems per replay) and the Dungeon Train (120 gems per win). Spend gems on 10× summons (450).
Gamepasses, Prices and Which Are Worth ItThere are 7 passes: Starter Pack (79 Robux), Big Backpack (99), VIP (349), Lucky Summons (399), 2x Gems (599), 2x Drops (599) and Premium Battle Pass (799). Best value: the Starter Pack for anyone spending at all, then Lucky Summons if you summon a lot (Mythic odds ×2).
Halloween UpdateThe official HALLOWEEN UPDATE 🎃 event runs from Oct 23, 12:00 UTC (8 AM ET / 5 AM PT) to Oct 26, 12:20 UTC. Redeem HALLOWEENSOON for 1,000 gems + 15 Trait Crystals now. The developer's event text only says 'New content' — we list what's confirmed below as players test it.

Units

Tier List: Best Units and Evolutions▶ VideoBest early unit: Jake — cheap ($50, up to 4) and full AoE from his 5th upgrade. Best evolutions: Alien Jake (black hole that holds whole waves) and King BMO; best boss killer: Marceline Beast. Late game: Candy Elemental Bubblegum, Jake the Lich and the summon Secret Magic Man. Weakest: Flame Princess, base Finn and Lady Rainicorn.
All Units (Heroes) and How to Get Them▶ VideoThere are 14 heroes: Rare Finn and Jake (starters), Epic Lady Rainicorn, Flame Princess and BMO, Legendary Marceline, Mythic Princess Bubblegum, Lemongrab and Billy, the Secrets Magic Man (summon, 0.05%) and The Lich (Lich's Lair), limited Ice King and Fire King, and Baby Finn (weekly Tournament top 3). Nine of them have evolutions.
All Evolutions, Recipes and Materials▶ VideoSeven evolutions cost 10 of the hero's material + 5 Enchiridion Pages + 1,000 gems at the Enchiridion Shrine. Each world's Act 5 drops one material per win (e.g. Ice Kingdom Act 5 → Sandwich → Alien Jake), so one evolution takes 10 wins. Pages come from Dungeon Train wins. Jake the Lich is different: 5 Lich Ooze + 10 Pages, no gems.
How to Get the Lich (Secret)▶ VideoThe Lich is a Secret hero you can't summon. Play Infinite mode: every 10 waves there's a 30% chance of a Lich Portal. Open it in the Tree Fort to fight in Lich's Lair — each win gives 1 Lich Ooze and a 5% chance of the Lich. Expect about 14 wins for a 50% chance. Lich Ooze evolves him into Jake the Lich.

Summoning & rerolls

Summon Rates and Odds Calculator% CalculatorEach summon costs 50 gems (or 450 for 10) at the Treasure Hoard. Rates: Secret 0.05%, Mythic 0.5%, Legendary 4.5%, Epic 24.99%, Rare 69.96%, and you're guaranteed a Legendary or better within 50 summons. A Mythic takes about 139 summons for a 50% chance (~6,300 gems); there's no known Mythic pity.
All Traits, Odds and Reroll Calculator% CalculatorThere are 11 traits. The best are Oh My Glob (0.2%: +200% damage, +20% range, +20% attack speed) and Hero of Ooo (0.8%: +30% damage, +15% range, +10% attack speed). Each reroll costs 1 Trait Crystal at Castle Lemongrab; there's no pity, so Oh My Glob takes ~347 crystals for a 50% chance.
Stat Grades (F to Z) and Juice Rerolls% CalculatorEach hero has three stats — Damage, Range and SPA — each graded F, E, D, C, B, A, S or Z. Z (0.2%) adds +35%, S (1.3%) about +30–33%, while B and C (41% each) add about +13–22%. Reroll at the Reconditioning Chamber: all three for 1 Juice, or lock one stat and reroll the others for 2 Juice.

Worlds & modes

All Worlds, Stages and RewardsThere are 7 worlds × 5 acts = 35 stages: Candy Kingdom, Ice Kingdom, Fire Kingdom, MO Factory, Castle Lemongrab, Nightosphere and Crystal Dimension (the game description still says 5 worlds and 25 stages). First clear: 150 gems + 1 Trait Crystal; every replay: 50 gems, and each world's Act 5 also drops 1 evolution material.
Infinite Mode, Dungeon Train, Tournament and PvPInfinite pays gems every wave and has a 30% chance of a Lich Portal every 10 waves. The Dungeon Train has 3 challenge cars that change every 30 minutes — each win pays 120 gems + 1 Enchiridion Page, first win per car adds 3 Trait Crystals + 2 Juice. The weekly Tournament ranks damage against a tower (top 3 get Baby Finn), and Battle Arena is 1v1 PvP.
