Era Ladder

Sort a scrambled set of wars, inventions and artworks into one true timeline — clear a rung to climb and draft a relic.

How to play

Each rung hands you a jumble of historical events to arrange in true chronological order. Reorder them until the sequence is correct to clear the rung and climb. Along the way you draft relics — special powers that reveal a year, swap two events, or lock a placement — to help with the harder rungs.

• Events range across war, invention, art and discovery
• Relics let you reveal, swap or lock placements
• Higher rungs mix more events and tighter dates

Controls

• Desktop: click an event to select it, then click another to swap or reorder; click to use relics
• Phone & tablet: tap to select and reorder — fully touch-friendly

Game modes

• Difficulty settings for the climb
• Daily shared ladder or endless Practice

Tips & strategy

• Place the events you're certain of first, then slot the rest between them
• Save reveal relics for the two events you genuinely can't separate
• Lock a correct placement before reshuffling the uncertain ones
