Era Ladder

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

• 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

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

• 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

Era Ladder drills chronological ordering across the historical eras, with a relic-draft progression that keeps you climbing.

• Skills: chronological ordering, historical eras, sequencing
• Best for: roughly grades 5–10 (ages 10–16)
• For parents & teachers: chronology practice with a progression hook.

Arranging a jumble of events into true order is chronology without any anchor to lean on.

Requiring the whole sequence, not pairwise calls, is the original demand.

Ordering a set is much harder than ordering a pair, and the reason is compounding: a single misplaced event breaks every relationship it participates in. It also punishes the commonest historical error, which is assuming that things that feel distant happened in the order they feel.

Era Ladder is an original chronological-ordering game with a roguelike relic-draft twist. It's free to play in your browser with nothing to download.
