Elementex

Elementex is a tactical tower-defense run. No worlds to grind. No campaign to crawl. One hex arena, one shot at the leaderboard, and every decision counts. Build between waves. Place towers on hex tiles. Bend the path with free walls. Tap a tower mid-wave to fire its skill. Lives reach zero, the run ends, and your best wave is the only number that matters. Fire beats Frost. Frost beats Nature. Nature beats Lightning. Lightning beats Fire. Hit a weakness for 1.5x damage. Hit a resistance for 0.7x. Read the wave, pick the counter, or pay for it. Every upgrade is bought with in-run gold. One tower per element — push its damage, its fire rate, or its range, each on a rising cost curve. No blueprints. No permanent unlocks to grind. Your build is what you can pay for, this run, right now. Every fifth wave is a boss. The boss drops a chest of three runes. You see every drop, every stat, every price, before you spend a single gem. Whatever you do not keep goes into the Recall Pool for seven days at +25 percent. Nothing disappears. Nothing is hidden. Runes you keep persist across runs. Combine two of the same rarity to climb to the next. Five rarities: Uncommon, Rare, Epic, Legendary, Mythic. Mythic is boss-chest only and carries a unique passive skill. An element-matched rune on its tower hits 20 percent harder. There is no end state. There is only the next wave, the global leaderboard, and how far you can hold the line. • Hex-grid tower defense with maze-builder pathing • Four elements, one rock-paper-scissors wheel (1.5x / 0.7x matchups) • One tower per element, upgraded along +DMG / +RATE / +RANGE with in-run gold • A defining passive and a tap-to-cast active skill on every element • Boss chests every five waves, transparent gem pricing, seven-day Recall Pool • A global leaderboard, one endless mode, three- to seven-minute runs • No loot boxes. No energy. No timers. No paid randomness.

Verdict

The call

The clearest difference is in-app purchases: SPHERE at none against Elementex's 5. SPHERE also leads on iOS requirement (13.0 vs 15.0). Elementex's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 4 months). On price and device support there is nothing between them.
