Not yours, not your cards. You never burn down a health total, you win by seizing the board. That single choice changes how every match is fought.<img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4825240/extras/d5b642f54ef4ea45cc1f2e4b35fd6680.avif?t=1782482071" width=1170 height=450 /><video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4825240/extras/1ee53bd6a6e5b12000c983abfe36cbf2.poster.avif?t=1782482071" width=960 height=402 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4825240/extras/1ee53bd6a6e5b12000c983abfe36cbf2.webm?t=1782482071" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4825240/extras/1ee53bd6a6e5b12000c983abfe36cbf2.mp4?t=1782482071" type="video/mp4"></video><h2 class="bb_tag" >No life points, win by domination</h2>Victory isn't a number reaching zero. You win one of three ways:<ul class="bb_ul"><li>Wipe the field: leave your opponent with no cards in play from the end of fifth round.</li><li>Deck them out: an opponent with an empty hand who can no longer draw loses on the spot.</li><li>Rule round 19: go the distance and the playerwith both more cards on the field AND a higher combined value wins. Lead one but not the other, and it's a draw.</li></ul>Every card you play is territory, not a hit to someone's health. Trades, tempo and board presence are the game.<img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4825240/extras/2e420c1b807fe4ca3307aabc934cce94.avif?t=1782482071" width=1170 height=450 /><video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4825240/extras/3ca373776439981fd536121de354caee.poster.avif?t=1782482071" width=960 height=402 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4825240/extras/3ca373776439981fd536121de354caee.webm?t=1782482071" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4825240/extras/3ca373776439981fd536121de354caee.mp4?t=1782482071" type="video/mp4"></video><h2 class="bb_tag" >How a clash is decided</h2>Combat is fast and fully automated. When two cards fight, the game compares their Total (TOT), the sum of five stats: ATK, DEF, HEL, DEX and MAP. But TOT is only the start:<ul class="bb_ul"><li>Estro matchups: every card is one of five Estro classes: Ardo (fierce attackers), Granito (impenetrable defenders), Armonio (healers and buffers), Illusio (assassin shadows) and Manpo (reality manipulators). An interaction matrix hands out bonuses and penalties depending on who attacks whom, send the right Estro into a fight and you can flip it before a point is counted.</li><li>The dice: both players roll a d6; the right result adds +5, so no clash is ever fully decided in advance.</li><li>Primary-double rule: overwhelm a card on the stat that matters and you win outright, ignoring TOT entirely.</li><li>Zones: an active Zone wraps the whole battlefield, buffing a matching Estro and bending the rules for both players.</li></ul><img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4825240/extras/c765d6dfabcd4bfabee57198a3a7b9a0.avif?t=1782482071" width=1170 height=450 /><video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4825240/extras/b8129bb584cfe1b3a86d24cd9c86cf3f.poster.avif?t=1782482071" width=960 height=402 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4825240/extras/b8129bb584cfe1b3a86d24cd9c86cf3f.webm?t=1782482071" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4825240/extras/b8129bb584cfe1b3a86d24cd9c86cf3f.mp4?t=1782482071" type="video/mp4"></video><h2 class="bb_tag" >Gifts</h2>Almost every card carries a Gift, a triggered ability that resolves automatically when it counts: on play, on destruction, or in response to your opponent. With more than 180 distinct Gifts in the box, steals, protections, revivals from the Incinerator and counters that turn a Gift back on its caster are all on the table. Gifts are where a pile of cards becomes a deck with a plan, and where the mind games live.<img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4825240/extras/da4080fc92c0c0d2f0376ae99b9ff9f4.avif?t=1782482071" width=1170 height=450 /><h2 class="bb_tag" >The Quantum layer</h2>This is the digital twist in the name. The entire ESTRO tabletop ruleset is intact, Quantum is built on top of it, never replacing it:<ul class="bb_ul"><li>Charge: every card you play banks Quantum Charge (up to 20).</li><li>Dominance: out-stat your opponent in 3, 4 or 5 of the five stats and you earn a x1, x2 or x3 multiplier for that clash.</li><li>Overload: spend your banked Charge times that multiplier and slam it onto the clash's total. It works on attack AND defense: a dominant card you control can repel an attack as easily as it can crush one.</li></ul>Quantum doesn't win the game for you, your board does. It's the risk/reward layer that decides who takes the fights along the way. Bank it, read the board, and unload at the exact moment it breaks your opponent.<img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4825240/extras/8f40e17b2315fa92676eb5d695a7cc48.avif?t=1782482071" width=1170 height=450 /><h2 class="bb_tag" >Build your deck if you want to play in deck mode and not random mode</h2>Assemble a 25-card deck from a pool of over 250 cards, pick 20 and let five be dealt at random, so every match opens a little differently. No duplicates, no booster-pack gambling: the full collection is your toolbox. The math is staggering: over 250 cards produce more than 16 decillion combinations. No two players will ever build the same way.<img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4825240/extras/4754f6886a798183bd6dbb882c658f64.avif?t=1782482071" width=1170 height=450 /><h2 class="bb_tag" >Modes</h2><ul class="bb_ul"><li>Campaign: a single-player run set in the ESTRO universe that teaches the system one duel at a time, chapter by chapter.</li><li>AI Battles: sharpen your decks against opponents across a range of difficulty.</li><li>Ranked PvP: climb a competitive online ladder against real players, season after season.</li><li>NecroToken: an advanced luck-equalizer mode: every card you lose hands you a NecroToken to bank and spend on an extra draw, an unbreakable shield, or a card pulled straight from your deck. Comebacks, weaponized.</li></ul><img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4825240/extras/3bce70d6d05e9aeddcb618fce130abee.avif?t=1782482071" width=1170 height=450 /><h2 class="bb_tag" >Fair by design</h2>The only store is in-game, and it sells cosmetics: card skins, battle effects, backdrops and card backs, bought with currency you earn by playing. No microtransactions. No real-money store. No pay-to-win. You win games at the table, not at the checkout.<h2 class="bb_tag" >One developer, the whole game</h2>ESTRO Quantum is a solo project. <h2 class="bb_tag" >Early Access</h2>ESTRO Quantum launches in Early Access, Necrotoken mode is only the start: more game modes are on the roadmap and will arrive during Early Access. Play to earn points, clear daily and weekly missions, and climb seasonal leaderboards to see who really runs the meta.No life points. Just the board, the clash, and the Overload you saved for the right moment.
