Waifu Sweeper Goes Free-to-Play on Abstract

Waifu Sweeper has switched to a free-to-play model on Abstract, the project posted on June 12, giving every new account a free Naki character and 300 energy to begin.

The game is published by YGG Play and built by the studio Raitomira, per PlayToEarn. It pairs Minesweeper-style tile logic with collectible anime characters in a skill-to-earn design, tasking players with using deduction to clear a board of hidden hazards.

The free-to-play change lowers the cost of entry. A new player now starts with a playable character and an energy balance at no upfront cost, which widens the pool of people who can try the board before spending anything.

Five days later, on June 17, the team launched a weekly Mine & Craft event built around reworked upgrade mechanics — including a higher maximum upgrade level, level-scaling upgrade costs, and the removal of the break chance on upgrades (now 0% for levels 1–20). The opening round runs June 17–23 with a three-winner prize pool, per waifusweeper.

Both updates arrived inside the same week, the second following the first by five days. Our read tracks Waifu Sweeper as Building.

What the Mine & Craft prize pool contains has not been spelled out: waifusweeper announced the three-winner pool without listing the rewards. Until the project says more, that detail stays open.
