Giant Simulator REBORN Summer Event Guide (2026)

The 2026 summer event is the first major seasonal update since Giant Simulator REBORN launched as a classic throwback. Part one introduced pet evolutions, beach-themed event pets, evolvable artifacts, and Shells as a new event currency. This guide covers every farming method, reward priority, and spending strategy so you finish the event with the strongest loadout possible.

What the Summer Update Added

Part one of the summer update brought three headline features to Giant Simulator REBORN: pet evolutions for event pets, a new batch of summer-themed artifacts with evolution tiers, and Shells as dedicated event currency. Mithril Games confirmed additional summer content is planned in later parts, so treat this guide as the foundation for an ongoing seasonal pass rather than a one-week flash event.

Shell Currency and How to Earn It

Shells are the event currency used to purchase pets, artifacts, and evolution upgrades from the summer event shop. You earn Shells through three main activities: collecting shell orbs scattered across the main town map, farming shell orbs inside the dedicated summer event area, and playing the mine race minigame where you hit balls into nets for bonus Shell drops.

Shell orbs on the original map are easy to miss but provide steady passive income during normal play sessions. Run a full map loop after each rebirth cycle to pick up free Shells without dedicating a separate farming session.

Mine Race Minigame

The mine race minigame inside the summer event area is the fastest active Shell farming method. Hit balls into the nets repeatedly to stack Shell rewards. Equip pets with Shell multipliers before entering — evolved event pets like Coco provide significantly higher Shell gain rates than standard pets. The minigame is accessible to all progression levels, making it the best entry point for new players who want event rewards without endgame stats.

Event Pets Worth Prioritizing

Every summer event pet provides Shell boost multipliers alongside standard coin, soul, and quest point stats. The standout pet is Coco, which currently outperforms the Bully pet that dominated pre-event tier lists. If you can only grind one pet during the event window, target Coco first.

Lower-tier event pets still offer strong Shell multipliers relative to their cost. Buy the best pet you can afford early, then save remaining Shells for evolution upgrades rather than spreading purchases across every pet type. See our pet evolution guide for stat comparisons between base and evolved forms.

Seashell pet line — strong mid-tier Shell multiplier
Treasure Map and Dory pets — solid coin/soul/quest coverage with Shell boosts
Evolve any purchased pet before buying the next tier up

Summer Event Artifacts

Summer artifacts ship in base and evolved forms. Base versions provide moderate coin, soul, and quest multipliers plus a Shell boost. Evolved versions roughly double every stat, making evolution the highest-value Shell investment after securing your primary pet.

Notable artifacts include the Old Shovel (1.4× coin/soul/quest, 1.05× Shells base → 2.8×/2.1× evolved), Seashell (2×/1.1× → 4×/2.2× evolved), Treasure Map (2.5×/1.2× → 5×/2.4× evolved), and Dory (3×/1.4× with higher evolved tiers). Prioritize evolving one core artifact before collecting duplicates of every type.

Optimal Event Progression Order

Redeem all active codes for free Gold before entering the event area. Farm shell orbs on the main map during normal play. Buy Coco or your best affordable event pet. Evolve that pet using Shells. Evolve one primary artifact. Push mine race sessions for remaining Shell income. Read our summer event map guide and pet evolution guide for zone-specific details.
