Calvinball — Fantasy Football Gone Rogue
Calvinball is a season-long fantasy football game built like a roguelike deck-builder.
Draft real NFL players as cards, equip Coaches that bend the
scoring rules in your favor, and climb one shared season-long leaderboard — no
head-to-head matchups, just your deck against the week.
Draft a deck, not just a roster
Your NFL players are cards. Draft a starting deck within a budget, then keep building it all season through a weekly waiver shop.
Coaches bend the rules in your favor
Equip up to three Coaches at once. Each one bends the scoring rules in a different direction: bonus points for a division, a doubled-or-nothing gamble on one player, a coach who rewards your bench.
One shared season, no head-to-head
Everyone in the league plays the same weekly matchup: the schedule. There are no 1-on-1 grudge matches deciding your fate — just your deck, your Coaches, and the scoreboard, all season long.
