Gigantamax Rillaboom Max Battle Day Guide (August 1, 2026)

Gigantamax Rillaboom Headlines the First August Max Event

Gigantamax Rillaboom Max Battle Day runs Saturday, August 1, 2026 from 2:00 p.m. to 5:00 p.m. local time, and it is the first time Gigantamax Rillaboom appears in Pokémon GO — with a possible Shiny for lucky players. All Power Spots host Gigantamax Battles during the window, Max Particle limits jump to 1,600, and the Remote Raid cap rises from 10 to 20. For Grass-type collectors and Max Battle fans, this is the marquee event of the first week of August.

Event Bonuses

Active for the full event (unless noted):

  • Max Particle collection limit increased to 1,600
  • All Power Spots host Gigantamax Battles
  • Power Spots refresh more frequently
  • Additional Power Spots active
  • 8× Max Particles from Power Spots
  • Up to three Special Trades for the day
  • Remote Raid limit raised 10 → 20 (Jul 31, 5:00 p.m. to Aug 1, 8:00 p.m. PDT)

On August 1, 12:00 a.m. to 5:00 p.m. local, two more bonuses apply:

  • 2× Max Particles from exploring (must first collect all Nearby Max Particles)
  • 1/4 Adventuring distance to receive Max Particles

Gigantamax Rillaboom: Typing & Counters

Gigantamax Rillaboom is Grass-type, so the counters that win are Fire, Flying, Bug, Ice, and Poison. Bring a strong Max-phase squad:

Role Top picks
Best Mega Mega Charizard Y, Mega Blaziken
Best Dynamax/G-Max Dynamax Charizard, Dynamax Moltres
Best Legendary Reshiram, Heatran
Budget Blaziken, Darmanitan, Volcarona

Because Gigantamax Battles need coordinated Max-phase damage, stack Max Mushrooms and bring at least one Fire-type attacker with a charged Max Move.

Event Ticket ($4.99)

The paid Timed Research grants:

  • 1 Max Mushroom
  • 25,000 XP
  • 6,400 Max Particles
  • 2× XP from Max Battles (during the 2–5 p.m. window)

It is only available in the in-game shop until 5:00 p.m. local on August 1 and cannot be bought with PokéCoins. The 6,400 Max Particles alone nearly refill your cap twice, making it the best value for players who plan to farm multiple Rillaboom.

Max Particle Strategy

Win the Particle economy with this loop:

  1. Collect all Nearby Max Particles before exploring to unlock the 2× bonus.
  2. Hit Power Spots early for the 8× drop before they refresh.
  3. Save a Max Mushroom for your highest-value Rillaboom attempt.
  4. Use Remote Raids to chain Power Spots outside walking range while the cap is raised.

Final Thought

Gigantamax Rillaboom is a top Grass attacker and a must-have for any serious Max Battle roster. Show up with Fire counters, top off your Max Particles, and use the raised Remote Raid cap to chain attempts. Happy hunting, trainers!
