Pokérium

Paused

Sixteen Kanto habitats and the Faraway Island open along one chain; each card names the Pokémon at home there, its best run and what opens it. A run is one clock on a field drawn from its seed: after the first minute most wild Pokémon are the habitat's own, the rest come from its ground, and each habitat further along the chain has tougher wild Pokémon. A run of six minutes in the Woodland opens the Meadow; most later habitats open after ten minutes in the one before; thirty minutes in one run marks a habitat mastered.

Habitats are switched between runs; during a run the buttons wait. Levels belong to the run: they reset when it ends. Mastery, coins, tickets, tokens, catches and the Pokédex are yours for good.

Every minute of a run pays PokéCoins for the seconds survived, the Pokémon beaten and the bosses, times the team's Fortune; tickets drop from rare kills and from bosses. For sale in coins: Poké, Great and Ultra Balls (200, 600, 1,200). A Mint (1,500) and the per-Pokémon upgrades are bought from a Pokémon's card in the Collection. Coins, tickets and tokens are earned only, never for sale.

The Kanto banner · five tiers, equal odds within a tier

Tickets drop on the run (one kill in four hundred, a boss's ten one time in three) and are never bought. A pull costs one ticket and wins one of the 151, drawn from your save: Common 45%, Uncommon 30%, Rare 17%, Epic 6.5%, Legendary 1.5% (the five legendaries and Dragonite), equal odds within a tier; the seventieth pull since your last Legendary is one; ten pulls for ten tickets always hold an Epic or better. A new species goes to storage with its own nature and a Pokédex entry; a species you own counts as one more copy toward its mastery and pays a mastery token. A pull with too few tickets or a full storage does nothing and says why. Adapted from PokéSurvivor's slot machine; the stars by base stats are Pokérium's.

Your Google account and this browser both have a save. Keep one; the other is kept as a backup (in the recovery export, or one step back in your account).

Every minute of a run is saved as one revision in this browser, and so is its end. A run is not resumable: closing or refreshing the page ends it, and what its minutes paid stays. Recovery never deletes: the original bytes are archived first and included in every export.

Your Pokémon hold a habitat's field. Wild Pokémon keep spawning from the field's grounds, faster and tougher by the minute; everyone attacks automatically. Everything here is how the game works today; nothing planned is listed.

1. One run, one clock. Wild Pokémon spawn from the field's tall grass, trees, water, rocks and ruins, each species from its own ground, faster and tougher every minute; the team fights on its own and the run ends when every member has fainted (or when you end it from the controls). Every field is drawn from the run's seed, so no two look alike.
2. The team levels as one. Every Pokémon beaten pays the team's XP pool; each team level puts three cards in the tray above the controls, taken at once while play goes on: a new move for one Pokémon, a level on a move it carries, a stat card for the whole party (Vigor, Power, Sprint, Reflexes, Armor, Synthesis, Learning or a Sitrus Berry), the key card a top-level move waits for, or the golden card that evolves it. One free reroll per run.
3. Every minute pays. At each minute mark the save pays every seated member the XP of the kills (with its mastery bonus) and the mastery XP, the bag the coins (times the team's and the account's Fortune) and the tickets dropped, and the Trainer the minute's XP. Levels reset when the run ends; mastery, coins, tickets, tokens, catches and the Pokédex stay.
4. End the run from the controls. A run is not resumable: closing or refreshing the page ends it with everything the minutes paid kept.

1. Bosses come on the minute. At 3:00, 6:00, 9:00, 12:00 and 15:00 a boss enters: a species of the slot's strength, never the same twice in a run, with its slot's HP grown by the clock; while it stands the crowd thins to a quarter and no surge comes.
2. From 30:00 the chain. Every five seconds a legendary joins, Articuno, Zapdos, Moltres, Mewtwo and Mew in turn, each with a quarter more HP than the last, for as long as the team stands. Nothing ends it but the fall.
3. Records open habitats. A run that lasts ten minutes in a habitat opens the habitat its unlock names; thirty minutes in one run marks it mastered, and the Faraway Island opens once every other habitat is.

1. Levels follow the species' real growth curve. Every wild Pokémon you beat pays every team member XP the moment it falls, and a level lands mid-run when its threshold is reached; a level raises its real base stats and teaches the moves its species learns at that level. Levels belong to the run and reset when it ends; the moves learned stay known.
2. Every Pokémon has a nature. Your starter is always Serious (neutral). A caught Pokémon rolls one of the 25 natures from the run that caught it (one stat +10%, another −10%, or none), the real stat formula counts it, and it never changes. Its Collection card shows it; wild Pokémon are all neutral.
3. Mastery is permanent, one Pokémon per species. You keep one of each species; every further copy (a catch, a pull) counts toward its mastery, pays mastery XP and one mastery token. Mastery levels come from play and copies: they raise the XP the Pokémon earns and every 5 add HP and damage. Its star comes from copies (★2 at 3, ★3 at 10, ★4 at 30, ★5 at 100): each star adds 4% to every stat, a step to each stepped upgrade's ceiling and multiplies its mastery gain; the ring shows the star. Tokens buy the Mastery shop's team-wide upgrades. Mastery, learned moves and a confirmed evolution stay when a run ends; an evolution into a species you already own is not offered.
4. Trainer XP is yours. Every minute survived pays Trainer XP; your Trainer level opens team slots and nothing else: it never adds combat power.

1. Four move slots per run. Each Pokémon knows every move its species learns by level-up up to its level, from the species' real list, and keeps them between runs; a new move is announced in the rewards when its level is reached. In a run it fights with up to four of its damaging moves: it starts on its strongest, and the cards add a known move to a free slot, raise a slot's move a level (five levels, +20% damage each), and at level five, once the stat card the move's type names (its key card) was taken this run, evolve it with a golden card into its + form (×1.8 damage). A spread move (Bubble, Discharge, Razor Leaf, Earthquake, Surf, Rock Slide and their kin, the moves the games aim at every opponent) hits up to three wild Pokémon in its range at once, four as a + move, each at three quarters of the damage. A status move is used once per run, and only when the fight is worth a turn: against a foe that would outlast two of the Pokémon's best hits (a boss always), a heal at half HP or below, Protect when a foe winds up at the user. Each costs a two-second turn.
2. The best hit is picked per target. Among its usable moves a Pokémon uses the one with the most expected damage over its cadence against that target: a move of its own type hits harder, the type chart doubles (×2), halves (½) or cancels (no effect) the damage, recoil counts against it. Every hit rolls 85–100% of its damage and has a 1 in 24 chance of a critical hit (1 in 8 for Slash and Razor Leaf) for ×1.5, shown as a number with !; every move hits; Take Down, Double-Edge and Flare Blitz cost their user a share of the damage dealt as recoil. A Pokémon faster than its target swings up to 10% more often, a slower one up to 10% less. Wild Pokémon follow the same rules, and every roll comes from the wave's seed, so a replayed wave rolls the same.
3. Named exceptions. Solar Beam winds up for two seconds before it lands; Super Fang halves the target's current HP; Endeavor brings the target down to the user's HP; Electro Ball grows with the speed gap. Power, type, category, accuracy, critical hits, recoil and Speed are active.
4. Stages, statuses and named effects. Growl, Tail Whip, Swords Dance and the other stage moves raise or lower a stat from −6 to +6 (shown as arrows on the row); Thunder Wave, Glare, the powders and the chances on Ember, Thunder Shock, Poison Sting and their kin inflict poison (an eighth of max HP per turn), burn (a sixteenth, and halved physical damage), paralysis (halved Speed, a 1 in 4 chance to lose a turn) or sleep (one to three turns); Bite, Air Slash and Hyper Fang can flinch a foe out of its windup. Roost and Synthesis heal half, Swallow by its Stockpile; Protect blocks every hit for a turn; Light Screen halves special damage to the team for five turns; Leech Seed drains an eighth per turn to its seeder; Wrap and Fire Spin trap for four to five turns at an eighth per turn. Electric Pokémon cannot be paralysed, Fire burned, Poison poisoned, Grass powdered. Everything ends with the wave. Weather, confusion, Whirlwind, Mirror Move, Tailwind, Rage Powder, Safeguard, Haze and the ability moves have no effect yet.

1. One partner a run. A run is fought by one Pokémon, your partner. Team shows it and your storage: pick a stored Pokémon and choose Make partner (or drag it onto your partner) to swap them. Everyone else waits in storage, and a change applies from the next run.
2. Collection shows every Pokémon you own with its level, mastery, moves, evolution and origin, and the Pokédex of species seen and caught. Picking one keeps your filters and scroll position. Nothing is ever released.
3. Evolution happens in a run. A Rattata that reaches Lv 20 on the field becomes a Raticate at once; a stone or trade evolution, such as Pikachu into Raichu, is a gold Evolve card in the tray from team Lv 30. When the run ends every Pokémon is its first form again, and catching any form of a line unlocks its first form.

1. Only alphas are caught on the clock. Once or twice in a few minutes an alpha enters with a boss's rustle: a quarter larger, gold-edged, three times the HP, half again the damage and five times the XP, a species you do not own four times as likely, and thirty coins when it falls. Its fall is the run's one throw at it: the field stops and you pick the ball, each with its real catch chance, or defeat it for its pay; the ball shakes as in the games; a miss lets it flee for good. A caught alpha joins storage with its own nature (a species you already own counts as a copy toward its mastery and pays a token). No other wild Pokémon is thrown at. Balls throw themselves: When a wild Pokémon is beaten down to a quarter of its HP, a ball is thrown at once if its species is not yet in your Pokédex or a team slot is open: it is caught and goes to storage, or it breaks free and leaves. The ball comes from the species' real catch rate: an Ultra Ball (×2) at 45 and below, a Great Ball (×1.5) at 120 and below, a Poké Ball above, or the nearest kind you hold. The chance and the ball are shown under the expected opponents before the wave. You start with ten Poké Balls; the Shop sells all three kinds at ₽200, ₽600 and ₽1,200.
2. Legendaries are bosses first. Articuno, Zapdos, Moltres and Mewtwo hold Seafoam Islands, the Power Plant, Victory Road and Cerulean Cave, Mew the Faraway Island. A boss is never thrown at until its habitat is mastered (wave 30 in one run); after that the policy throws at it like any wild Pokémon, at its real catch rate of 3, with the strongest ball you hold.
3. The gacha holds all 151. Tickets drop on the run (one kill in four hundred, a boss's ten one time in three); a pull costs one and wins one Pokémon of the Kanto banner by tier (Common 45%, Uncommon 30%, Rare 17%, Epic 6.5%, Legendary 1.5%), the seventieth pull since a Legendary is one, and ten pulls hold an Epic or better; a species you own pays coins instead. Reach it from the Shop. Tickets are never for sale.

1. Saves happen every minute. Each minute mark and the run's end commit their receipt; a run is not resumable, so refreshing or closing the page ends it with what its minutes paid kept. If a save fails, the receipt waits and retries at the next one or from Save & recovery, which can also export a recovery copy, restore the previous revision or start a fresh save with the original kept.
