Starguard: Evo Merge TD players can redeem official promotional gift codes throughout October 2026 to secure premium in-game gems, turret blueprints, gold reserves, and crucial summoning catalysts distributed directly by developer ONDI TECHNOLOGY JSC across mobile platforms. According to verified reports from GamingonPhone, the tactical tower defense title has refreshed its redemption roster to celebrate seasonal milestone campaigns. Active coupon keys include STARGUARD2026, EVOMERGE, and TDOCTOBER, granting players substantial piles of diamonds alongside high-tier unit summoning tickets. Players claim these rewards directly within the mobile application by navigating to the player avatar menu, selecting settings, and entering the exact voucher string inside the redemption prompt. Because developer gift codes operate under strict inventory redemption limits and tight expiration clocks, mobile strategists must activate them promptly to bolster their frontlines. Free resource injections give free-to-play commanders an immediate boost against surging enemy swarms in advanced wave stages. Similar to tactical title launches like the [Azur Promilia Release Date Set For November [Confirmed]](/news/azur-promilia-release-date-confirmed-537), reward mechanics directly shape early player retention and community engagement across global leaderboards.
